2" Plain Bevel Seat Rubber Hose Adapter

Eagle 2" Sanitary Plain Bevel Seat Rubber Hose Adapter

Enhance your hygienic setups with our 2 inches Plain Bevel Seat Rubber Hose Adapter which is made from food-safe 304 or 316L stainless steel and certified by 3A. Our fittings make sure that your 2 inches connection is leak-proof for high-capacity hygienic process operations, as well as in the food industry, pharma industry and brewing industry. The fitting is designed for reliability, resistance to corrosion and affordability which is why they are ideal for those who either have medium or larger facilities and who want to use flexible rubber hose 2 inches with their solid Tri-Clamp pipeline.

Product Overview

A 2-inch size is the most common rubber hose connector in the field of sanitary processing because it provides an ideal combination of flow capacity, ease of handling, and the cost of fittings. It acts as a common connector for product transfer lines, CIP feeding lines and drain lines, and pump connections in producers that work batches of several hundreds to several thousands liters. The smooth bevel seat is designed in compliance with standard 2-inch Tri-Clamp ferrules, ensuring a smooth connection and hygienic properties from thermal cycling. The barbed end has been specifically created for rubber sanitary hoses with a retention characteristic that holds the thick and heavier hose material while ensuring the smooth internal transition of the hose for proper CIP drainage.

Frequently Asked Questions

Why is the 2-inch size the most common rubber hose adapter?

The usage of two-inch diameter creates a perfect equilibrium among the flowcapacity of the pump, weight of the pump hose, and pricing for the fittings that is adequate for most medium sanitary processes. When utilized at standard CIP velocity of 5 feet per second the two-inch pipe allows to achieve a flow rate of around 50-55 gallons per minute, which is enough to transfer 2,000 liters of material in less than ten minutes and at the same time allows to keep the hose light enough to be lifted by one person. Moreover, this is the default size of fittings in many positive-displacement and centrifugal pumps with 5-20 HP capacity making it therefore the standard type of connection in the whole industry.

How does the flow capacity of a 2-inch rubber adapter compare to a 2-inch Tri-Clamp connection?

The barb of the rubber connector has an internal diameter that is slightly less than the full 2-inch tri-clamp size, owing to the presence of the barb wall, which takes up some cross-section space. The amount of flow restriction here is not significant either — it usually accounts for a 5–8% decrease in effective area compared to yet another section of straight 2-inch tubing. For many sanitary transfers this minor decrease is no big issue compared to a resultant pressure drop through the flexible rubber hose, which often creates the major restriction in any hose-and-pipe assembly.

What type of clamp should be used to secure the rubber hose to the adapter?

To install a hose clamp, you will need either a stainless steel system worm drive or a heavy-duty bolt type that fits over the rubber hose’s outside diameter. It should be positioned behind the retention ridge on the barb shank and done up to the hose manufacturer’s specifications, which will ensure that it is tight enough to keep the hose in place during operation but not tight enough to create any damage. Make sure to tighten it again after a couple of CIP cycles as the rubber is prone to compression.

Is the 2-inch rubber adapter interchangeable with a 2-inch Tygon adapter?

No. The rubber adapter made of 2 inches differs from the Tygon hose adapter made from 2 inches in terms of some barbs. The barb of the rubber adapter is longer and has a ridge that is more capable of holding the rubber hose. In contrast, the barb of the Tygon hose adapter is designed to accommodate the thinner and stronger wall of Tygon tubing. Using a Tygon adapter with rubber hose may result in the hose coming off under pressure.
