Whether you’re managing a commercial build, upgrading a wastewater system, or simply searching for “plumbing supply near me,” choosing the right plumbing fittings manufacturer makes all the difference.
From butt weld pipe fittings in industrial systems to PVC elbows under your kitchen sink, fittings are the connectors that make modern plumbing possible. But not all manufacturers serve the same markets—or deliver the same level of quality, certification, or price stability.
This guide breaks down the types of fittings available, leading manufacturers, pricing expectations, materials, and how to choose the right supplier for your project.
What Are Plumbing Fittings?
Plumbing fittings connect, redirect, control, or terminate pipe flow. They are essential components in:
- Residential water supply systems
- DWV plumbing fittings (Drain, Waste, Vent)
- Sewer systems (including 4 inch sewer pipe fittings)
- Industrial and sanitary processing lines
- Gas and compressed air systems
A complete plumbing fittings chart typically includes elbows, tees, couplings, reducers, caps, unions, adapters, and valves.
