Dual Arch Rubber Expansion Joint

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 include anti-corrosive rubber compound fitting by metal float ASA flange connection sizing 1¼ to 40 inch.
