MODEL 79 “WILDCAT” COUPLING

The Shurjoint Model 79 “Wildcat” coupling is designed to mechanically to join plain-end or beveled end carbon steel pipe.  The “Wildcat” couplings can be used for a variety of applications including mining, process piping, manifold piping and oilfield services.  The “Wildcat” couplings feature case-hardened jaws* within the housings and large diameter heat treated track bolts that when tightened securely grip the pipe surface.  As with grooved couplings, a C-shaped rubber gasket effectively seals the pipe ends. (* For sizes larger than 14” (350 mm), jaws are made of 17-4PH stainless steel.)

The Model 79 coupling is recommended for use on carbon steel pipe with a hardness less than HB150, not recommended for stainless steel, plastic, HDPE cast iron or other brittle pipe.

Gaskets are available either in Grade E EPDM for water services of -29°F to + 230°F (-34°C to + 110°C) or Grade T Nitrile for oil services -20°F to +180°F (-29°C to +82°C).

*Working pressure is for plain-end standard wall steel pipe with hardness less than HB150.
