Rubber expansion joints are designed to relieve mechanical stressors; they can be made from many materials including stainless steel, Polytetrafluoroethylene and braided flexible metal. Rubber expansion joints are particularly beneficial due to its flexible nature, which makes them suitable for many functions, including the absorption of sound, thermal energy and shock. Our rubber expansion joints are specifically designed to reduce the need for maintenance, repair and manual assistance.

Proco Series 233-L and Series 234-L Rubber Expansion Joints are designed for piping systems that experience large lateral offsets due to settlement. They are low-profile expansion joints, and are available in a triple-arch or quadruple-arch design, featuring a built-in reinforcing ring at the top of the arch to provide extra stability for lateral movement. Also available in a filled arch, the Proco Series FA233L and Series FA234L are designed specifically for piping systems that carry heavy solids.
Proco Style 234-L
Low-Profile Quadruple-Arch w/Reinforcing Ring for Lateral Movements Up to 8″
Proco Style 233-L
w/Reinforcing Ring for Lateral Movements Up to 4″
Proco Series 240/242 molded spherical rubber expansion joints are designed to be used in piping systems. These molded, single sphere designed bellows are inherently stronger than conventional hand-built style spool arch types. The spherical design’s “flowing arch” reduces turbulence as well as sediment build-up.

The Proco Series 271 Spool-type rubber expansion joints feature a super wide flowing arch design which is self-cleaning. This makes it a perfect choice to use where slurries are present, eliminating the need for a filled arch design.
