Features & Benefits
Multi-Directional Movement
Single arch absorbs axial expansion, lateral offset, and angular misalignment simultaneously in one compact body.
Vibration and Noise Isolation
Elastomeric body dampens pump vibration and fluid-borne noise, protecting downstream equipment and building structures.
Integral Rubber Flange Face
Moulded rubber flange with sealing beads eliminates need for separate gaskets and provides reliable sealing on mating flanges.
Vacuum Rated
Steel wire helix prevents arch collapse under vacuum or suction conditions, maintaining flow area and preventing damage.
Limit Rod Protection
Optional limit rods prevent over-extension during pressure surges or pipe settlement, extending joint life.
