Rubber Expansion Joint with Threaded Union

Rubber expansion joints are used as the compensator in rigid piping systems. Allowing maximum deflection, elongation and compression, rubber expansion joints are the perfect choice to absorb movements, compensate for pipe misalignment, and reduce vibration and system noise.

Our dual arch rubber expansion joints with threaded union include anti-corrosive rubber compound fitting by union connection sizing ½ to 3 inch.
