The Beaver Single-Arch Moulded Rubber Expansion Joint has a spherical design that gives it four-way movement. It allows for axial compression and extension, lateral deflection, angular and torsional movement.

Aside from absorbing directional movement, this expansion joint also dampens noise and vibration caused by mechanical equipment. It can be used to correct minor pipe misalignments during installation and relieve pipe stress caused by thermal expansion or mechanical movements.

This rubber expansion joint is suited to transporting fluids, slurries, or gases. Steel reinforcement embedded in grooved rubber ends provides strength under pressure or vacuum. Spherical design distributes internal pressure in all directions, reduces turbulence, and prevents sediment build-up.

Choose from a range of inner tube and outer lining materials to suit your media and site conditions.
