Poly Shouldered Ends and Couplings

This is a highly effective pipe joint, using two identical half housings to fully enclose a specially designed lip seal gasket and lock behind a raised shoulder formed on the poly weld on end, providing the joint with end-load bearing capabilities. During assembly the seal lip is fitted over the shoulder. The housing compresses the gasket and internal pressure reinforces the sealing.

Bolted Couplings
Material: SG iron . Bolts & Nuts: Metric; grade 4.6 to AS1112.
