Rubber Expansion Joints

Rubber Expansion Joints

UIP rubber expansion joints provide time-tested ways to accommodate pressure loads, relieve movement stresses, reduce noise, isolate vibration, compensate for misalignment after plants go on stream, and prolong the life of motive equipment. Hand-crafted rubber expansion joints are available in single – and multi-arch designs and are custom-engineered to fit your application requirements.

Available options include PTFE-lined, eccentric reducing, concentric reducing, filled arch, lightweight and off-set configurations. They can be designed to operate up to 200 psi and withstand temperatures up to 500º F. Sizes available from 1/2″ to 144″.
