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.

1.Examine the pipe ends to ensure they are round, smooth, free of dents and score marks. Ensure they are within the specified tolerance for that material type. Any weld beads/marks must be ground smooth while correctly maintaining the correct surface profile. Ensure that pipe ends for engagement into coupling are free from rust, scale or any other foreign matter that may affect the performance of the coupling (Fig. 1).
2.Align the pipes to be joined, ensuring they are concentric. Mark both pipe ends at a distance of half the clamp length minus half the setting gap of the coupling to be used (refer table on page 1 and Fig. 2). Lubricate the surfaces of the sealing gaskets with approved lubricant. When joining two pipes with varying outside diameters, position the coupling end with the nuts on the pipe with the smaller outside diameter.
3. Adjust the gap setting (Fig. 2) between the pipe ends for appropriate coupling.
4.Using the markings as a guide on the pipe ends, slide the coupling to a central position over the pipe ends. For ease of installation, rotate coupling so all bolts and nuts are accessible.
5.When tightening coupling, bolts should be tightened in a diametric star pattern (Fig. 3). Give each nut 1 – 2 turns at a time to evenly engage the end rings and gasket assembly. Using a torque wrench, all bolts must be properly tightened to the correct torque provided in the table on page 1. Retension all fasteners after 30 minutes to compensate for loss of tension through gasket relaxation. It is recommended that an anti-galling lubricant be applied to stainless steel or galvanised fasteners, as required.
