Piping systems often experience movements caused by thermal expansion, equipment vibration, or pressure pulsations. When these movements cannot be accommodated by the piping system itself, expansion joints provide an effective solution.

An expansion joint is a device, typically composed of flexible bellows, designed to absorb movement while containing both pressure and the medium flowing through the system.

Rubber Expansion Joints are flexible connectors made from natural or synthetic elastomers, fluoroplastics, and fabrics, with optional metallic reinforcements. They are engineered to absorb system movements while maintaining pressure containment and medium integrity.
