Tapered Rubber Expansion Joints & Other Rubber Expansion Joint Styles
The purpose of a tapered rubber expansion joint is to join two pipes with unequal sizes or diameters, transitioning from a larger diameter on one side to a smaller on the other. These rubber expansion joints are often used at pump outlets or on other equipment where reducers are required. At UIP, we offer both concentric and eccentric tapered expansion joints in a variety of diameters. EPDM Concentric joints are now available from stock and are ready to ship same-day. Eccentric, or offset joints can be special ordered based on the alignment and dimensions of the piping systems. Contact our engineering department for help with your piping project.
UIP’s Rubber Bellows are designed to EJMA (Expansion Joint Manufacturers Association) Guidelines and FSA (Fluid Sealing Association) Standards.
Sizes – 1″ to 120″.
