Unrestrained Mechanical Coupling

Unrestrained Mechanical Coupling

Our range of unrestrained mechanical couplings comply with AS/NSZ 4998 for potable and non-potable water applications.

The Clover unrestrained mechanical coupling range is suitable for connecting and repairing cold water piping systems.

  • Three bolt coupling design up to DN150 for fast field installation.

  • Can be installed without disassembling which makes installation quick and simple.

  • Captive bolt head for one spanner operation, simplifying field assembly.

  • Certified to AS/NSZ 4998.

Overview

Our high strength 316 stainless steel mechanical couplings join a wide range of pipe materials and can be used to join pipes with equal or differing outside diameters (Up to 27mm). This makes the coupling ideal for joining PVC-O, PVC-M, PVC-U, GRP, ductile iron, asbestos cement, and steel.

While this product is manufactured with a lightweight 316 Stainless Steel barrel and fasteners, and feature wedge shape EPDM Seals, it is not recommended for use on polyethylene pipe.
