Stainless 304 316 Grooved Coupling with 

Viton Seal/Fluororubber Gasket

SS Rigid/Flexible Coupling is a Stainless Steel coupling made of ASTM A-743/A743M cast Stainless Steel which is the cast equivalent to 316/304 Stainless Steel. It is designed for installation on grooved Stainless Steel Schedules 10, and 40 pipe and grooved fittings. The stainless steel material is suitable for a variety of aggressive corrosive environments. The coupling provides a joint connection by firmly gripping along the circumference of the pipe grooves. It is capable of pressures up to 300 psi depending on pipe size and wall thickness.

Stainless Cast Couplings 20NB through to 300NB with Viton rubber gaskets. The Fluoroelastomer  is for temperature range +20°F to + 300°F/–7°C to +149°C. May be specified for many oxidizing acids, petroleum oils, halogenated hydrocarbons, lubricants, hydraulic fluids, organic liquids and air with hydrocarbons. NOT COMPATIBLE FOR USE WITH HOT WATER SERVICES OR STEAM SERVICES.
