In 2026, issues surrounding plumbing fittings are heavily impacted by a mix of old and new forces. On one hand, the plumbing fittings business will continue to rely on the traditional foundation of the industry which handles standard home maintenance, replacements, and new construction; however, due to the limited amount of manpower available combined with skyrocketing costs of materials, its growth potential will be constrained. On the other hand, the plumbing fittings business is now experiencing unprecedented technological advances. Just ten years ago, plumbing specialists could not have foreseen the rapid development of artificial intelligence (AI) data centres outpacing (and replacing) air-cooled systems and their growing reliance on liquid-cooling which employs stainless steel piping, leak-free connectors, and the distribution of liquids through plumbing systems. Additionally, the various systems have different economic models, timing and specifications, thus both must be understood to successfully develop plumbing fittings for either market.
In terms of size, the plumbing fittings sector continues to grow steadily and is forecasted to reach between $36 billion and $41 billion globally in 2026 whereas the overall sanitary metal products sector is forecasted to be approximately $76 billion. There are many factors that have contributed to the above-mentioned projections for 2026, including the ongoing shortage of skilled labour (due to an aging workforce), the increasing adoption of stainless steel and PEX products, the increased scope of the newly enacted International Plumbing Code (which has added new water efficiency and greywater standards), the introduction of 'smart' fittings with leak detection, the development and commercialisation of prefabricated products, the growth of e-commerce channels, and the approximately 30% increase in cost of plumbing materials since the start of the COVID-19 pandemic.
The Market in Numbers
Estimates of the market for plumbing fittings vary considerably because analysts disagree about where to draw the line. Some analysts count only piping and valves while others include such items as faucets and sanitary ware. Therefore, it is impossible to arrive at a single, reliable estimate of this market; one can only arrive at a range of estimates.
| Scope | 2026 value | Forecast | CAGR |
|---|---|---|---|
| Plumbing pipe fittings (global) | $36.8-39.9 billion | $62-69.5 billion by 2034 | 5.6-8.4% |
| Plumbing fittings including faucets and valves | $41.4 billion | $63.8 billion by 2035 | 4.92% |
| Sanitary metal ware | $76.24 billion | $125.02 billion by 2035 | 5.65% |
| US plumbing services market | $169.8 billion | — | — |
There are major similarities between many of the numbers related to hydraulic components in various sources, so they can appear in forecasting. According to estimates, taps account for about 34% to 36% of items used in construction. Valves and tubing fittings account for approximately 29%. The rise in the demand for fittings made of stainless steel has been approximately 26%, due to their durability and resistance to corrosion. It is the Asia-Pacific region alone that represents about 43% of total consumption. Despite the presence of the leading five companies producing hydraulic parts, which have approximately 51% of the production volumes, the market is less concentrated than might be expected.
1. The Labour Shortage Hardens
The state of affairs underlines the situation described above. The USA is expected to lack about 550,000 plumbers by 2027, while the Bureau of Labor Statistics predicts the appearance of around 44,000 job offers every year until 2034. Approximately 23-25% of currently employed people are over the age of 55, while the working plumber age averages around 41-42 years old.
Consequences of the situation are also clear, as the median salary of a maintenance plumber is $62,970 a year, companies spend over $5.3 billion each year on hiring and training activities and high-performing companies in the housing sector achieve a ticket turnover of $300-500. For manufacturers and distributors supplying fittings, it matters at structural level rather than at cyclical level. Deficiency of labor increases the value of everything that can reduce installation time.
2. The Material Shift to Stainless and PEX
The mix of materials seems to be going in two directions at once, both of which favor fittings over raw pipe.
On the potable-water side, PEX continues to gain market share over copper in residential and light commercial applications because of lower costs, faster installation, and higher resistance to corrosive and freeze damage. The fittings ecosystem associated with PEX – crimp, clamp, and push-fit – has developed into a separate market segment. Installation labor is the greatest contributor to the overall cost in both cases.
On the industrial side, stainless steel is becoming the material of choice. The market for stainless fittings has grown by around 26% globally, while the usage of stainless steel combined with brass accounts for approximately 60% of industrial plumbing installations. The reasons for this development are corrosion resistance, easy cleanability, longer lifespan, along with far wider compatibility with various process liquids than carbon steel or plastic.The choice between 304 and 316L is the specification decision that follows, and it is driven by chloride exposure, temperature, and cleaning regime rather than by price — the differences that matter are set out in our guide to 304 versus 316 stainless steel selection.
Where brass and stainless compete directly — fittings and valves in potable and light process duty — the decision usually turns on dezincification resistance, pressure rating, and cost, which is a comparison we cover in our article on brass versus stainless steel pipe fittings.
3. AI and Liquid Cooling: The New Demand Centre
This is an evolving trend that has most changed the demand situation in the last two years and which is worth the greatest consideration because it is the one in which the abilities of a plumbing fittings supplier come into contact with a completely new usage.
The density of racks is the forcing function. Cooling designs of data centers have been made for rack densities of 7-15 kW. Yet, racking of Blackwell GB300 consumes 163 kW. Racks of Vera Rubin NVL144 generation consume over 300 kW with further expectations of the Rubin Ultra configuration reaching 600 kW. It is impossible to use air cooling to expel that heat, and this is why the industry has been forced to use liquid coolants instead of just treating them as a choice.
The financial implications are huge, and many analysts pay attention to this. Dell'Oro Group says that the market of liquid cooling for data centers practically double the size in 2025, approaching $3 billion of revenue and projected to hit $7 billion in 2029. Grand View Research estimates that the amount of the liquid cooling market will reach $6.7 billion in 2025 and go up to $8.2 billion in 2026 with a CAGR of 21.8%. Mordor Intelligence and Straits Research say that revenues in 2026 will range between $6.5 and $6.8 billion. Immersion cooling, the separate market segment was valued at approximately $2.64 billion in 2025 with expectations to achieve $16.55 billion market size by 2034. Central to this process is capital spending: the top nine cloud service providers increased capital expenditure by 79% to approximately $830 billion.
Thus, what does a plumbing fittings company have to do with this? A lot! Liquid-cooled data centers are just fluid distribution systems, while other details used to transport the coolant between the cooler and the racks such as CDUs, cold plates, quick connectors, and piping were developed by hygienic process engineering ages ago.
| Requirement | Why it matters in liquid cooling | Where the capability comes from |
|---|---|---|
| Clean, crevice-free bore | Debris and biofilm block microchannel cold plates and degrade heat transfer | Sanitary and hygienic piping practice |
| Corrosion resistance | Coolant chemistry, mixed metals, and long service life rule out carbon steel | 304 and 316L stainless |
| Zero-leak joints | A leak inside a server rack destroys hardware; quick connectors are specified for more than 5,000 mating cycles without leaking | Precision mechanical design and seal specification |
| Leak-tight threaded and clamped connections | Thread-standard mismatches are a leading cause of leaks at commissioning | Correct NPT, BSPT, and clamp standards |
| Documented material grades | Specifiers must prove compatibility with the coolant and the warranty | Material certification and traceability |
The quick connector segment illustrates the direction of travel: one analysis put the global quick connector market for liquid cooling at $293 million in 2026, growing toward $748 million by 2032, with zero-leak performance and high mating-cycle endurance as the defining specification. Manifold and CDU markets are forecast in the billions.
The practical takeaway for anyone specifying piping for this industry is that the issue regarding fittings is not a question of commodities. The coolant systems cannot afford the compromises acceptable for potable water systems, as the elements involved in shipping the hygienic process piping will be stainless tube and pipe, clamp fittings, and sanitary valves.That is the category we manufacture, and the components that make the transition — described in our primer on what a sanitary fitting is — are increasingly specified in data centre mechanical rooms alongside the traditional food, beverage, and pharmaceutical applications.
The tri-clamp connection in particular has become a practical choice for manifold and CDU work, because it can be assembled, inspected, and broken down without cutting pipe. The sizes and configurations involved are covered in our guide to tri-clamp fittings under $80.
4. Water Efficiency Becomes Regulation
The move from water conservation being a theme for marketing to being a matter for compliance creates a lot of work because compliance is not optional.
The figures associated with the issue provide the size of the scope of the problem: the leaks at home consume nearly 900 billion gallons of water every year in the USA, whereas landscape irrigation wastes around 50 percent of the 8 billion gallons of water used for this purpose daily. The greywater recycling undergoes a significant increase of around 6.7 percent annually, while North America possesses approximately one-third of the market, and the combination of the rainwater collection and grey water reuse technologies can bring the total demand for potable water down by 40-60 percent which matter for owners of commercial properties going for net zero water objectives.
With regard to fittings, this has a profound impact on the situation. Greywater and rainwater harvesters require special materials that are suitable for non-potable waters and backflow prevention systems to ensure that the supply of drinking water is secure, as well as fittings which can be cleaned throughout time when biological materials accumulate in systems. Water-saving sanitaryware requires proper fittings and plumbing fixtures arrangements, and the building with dual water supply need to separate system of distribution. This is a specification-based type of demand and the necessary equipment is not consumables.
5. Smart Fittings and Leak Detection
The insurance industry has played a large part in the transition of connected plumbing from being a new idea to one considered as standard. Currently, average claims for water-related damages are about $11,000 – $14,000, which makes automating the shut-off process something that homeowners are more than willing to experiment with, especially those who have already had a case of a ceiling collapse.
Market data supports the trend: according to various analysts, smart bathroom segment would be able to demonstrate CAGR between 12.1% and 13.7% until 2030-2035. The development of smart toilets alone will result in the market volume of $15.76bn in 2030, which would be achieved due to the introduction of touch-less control and self-cleaning features. The commercial segment saw 22% growth of demand for sensor-based and touch-less solutions. What is more, more than half of consumers prefer to use touchless sanitary ware.
This technological advancement demonstrates that electronics are becoming an integral part of plumbing systems, with flow sensors, motorised isolation valves, pressure transducers and control modules getting integrated into the buildings’ management system. For fittings manufacturers, it means that they need to promote goods which comply with the need for sensor ports and serviceable cartridges. In addition, the maximum reliability of those fittings in monitored systems has to be ensured, since the electronic systems only notify about the failure but do not prevent the mechanical one.
6. Prefabrication and Modular Assemblies
Prefabrication is the important solution to labour shortage in the industry and changes the nature of how fittings order look like. Instead of manufacturers supplying parts to contractors who put them together, manufacturers supply ready-made parts known as modules like valve trees, manifold assemblies, plant room skids and bathroom pods which are made and tested in the factory with higher productivity and better control of quality.
One example from other spheres showing the efficiency of using composite fittings is that with these parts installation time is reduced by 15-20% compared to using steel. Taking this principle to the level of fully prefabricated construction allows saving more hours on the site.
Procurement-wise buyers buy more and more assemblies instead of parts moving the focus of attention from price to engineering capabilities, testing procedure and documentation of the pressure test. This favors manufacturers that have in-house facility for welding, assembling, cleaning and certification which is exactly what hygienic fittings manufacturers have.
7. Code Change and Compliance
The changes that were made to the International Plumbing Code for the year 2024 are related to greywater and wastewater reuse, pipe-sizing provisions, and additional requirements for backflow prevention. In addition, state water conservation laws make the process more complicated and create additional paperwork in order to prove compliance with different inspections and permits.
The deadline for adapting to the changes in standards of fittings is approaching fast. The changes in code concerning pipe sizing will also invalidate existing standards. Furthermore, various new requirements pertaining to backflow prevention may also make it necessary to do installation work that was not required before.The standards framework that governs hygienic and process piping follows a similar pattern, and staying current with it is a matter of specification discipline rather than interpretation — the standards that apply are catalogued in our overview of sanitary pipeline standards.
8. Material Cost Pressure
There has been almost a 30% rise in material prices from 2021 to 2025 and manufacturers are contending with uncertainty and instability in material costs. As per experts, the annual volatility for products such as polyethylene and alloys of metals is around 10 to 12% in a fiscal year. Approximately 37% of manufacturers consider fluctuations in prices of raw materials to be the most important barrier they face; around 32% cite issues related to supply chains as a major cause of problems.
One measure adopted by manufacturers to overcome material uncertainty is hedging; they enter into long term supplier contracts that propose prices which are indicated in the contract and are increased only at a certain point.
9. Ageing Infrastructure Renewal
The cost of updating old water system infrastructure in the US has an estimated price tag exceeding $1 trillion over the next two decades. Many water pipes put in place during the 1950s are currently on, or beyond, their expected life span. Therefore there is likely to be a great long-term demand driven by components such as fittings, valves, and connecting hardware.
Renovation and retrofitting provide protection against booms and busts in construction cycles. In the developed market, the average age of the housing stock is over 30 years. Special fittings are required for trenchless repair methods such as pipe lining and pipe bursting.
10. Channel Shift and E-Commerce
In 2024, the e-commerce revenues of plumbing products surged approximately 29%, with e-commerce gaining a significant share of this market. Such growth has been supported by the transparency of pricing, availability of niche products and contractors' openness to ordering supplies digitally.
However, this brings about qualification issues. For commodity fittings and replacement parts, online channels work well, while they are not very reliable for all certification, material traceability and warranty issues. Counterfeit and wrongly described products is an issue in a wide range of industries, particularly in how fittings that lead to water damage become useless and turn savings made by untrustworthy suppliers into a farce. Therefore, it is reasonable to buy commodities at the lowest prices, while important components should be purchased from verified suppliers with proper qualification and the ability to provide evidence of their offering.
What It Means for Buyers
Based on the above-mentioned list of twenty trends, some practical conclusions can be drawn.
- Specify the material in terms of its application and not in terms of the costs. Stainless steel, PEX, and brass may be the best choices in different cases, and the cost of the wrong decision may become clear after years.
- Buy efficiency in case if the labor is scarce. Push-fit, clamp, and prefabricated solutions are more costly in terms of units. However, they allow saving on man-hours.
- Acknowledge that liquid cooling is a separate segment. If you are providing the mechanical systems for the data center or any other application, using stainless hygienic material is always a good decision, and its demand is increasing faster than any other.
- Pay attention to documents. With the increase in material costs, different certificates of material, records of pressure tests, and etc. gain in their importance.
- Be prepared for new regulations. Greywater, rainwater, backflow, and pipe-sizing alterations bring along new types of work in terms of compliance, and companies that know the current regulations will have greater quotation.
- Calculate not the cost of a single unit but that of the total assignment. A fitting that is cheaper and breaks down after five years is more costly than the one that provides thirty years of service.

Conclusion
The plumbing fittings industry will experience two trends in the near future. The first trend is the continued growth of the traditional plumbing market due to a shortage of skilled workers, outdated plumbing systems, the use of newer plumbing products which enforce water conservation, and the increasing trend of converting plumbing systems from manual control to automatically controlled systems leading to continued growth for plumbing fittings at a consistent rate (mid-single digits) and the introduction of compliance-related projects. The second trend is the introduction of new technology related to the growing use of artificial intelligence computing with a focus on liquid-cooled vs air-cooled models. These new technologies will create an increase in the demand for new sanitary products ("sanitary devices"), and subsequently, will create new markets. The discipline that is paying off for both sectors of the plumbing industry is similar to the past methods used in this particular industry. For example, when purchasing plumbing products, focus on using the proper materials that meet your project requirements rather than based solely on price, and selecting the best installation for your plumbing projects based on the difficulty in finding skilled labor to conduct this work. Evidence from the past indicates that it is necessary to document all pertinent information regarding product materials and to conduct pressure testing on the product before buying. The plumbing fittings are not the most visible component of a plumbing system, however, they have a direct impact on the functionality of the plumbing system.
