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 EPDM gaskets. Temperature range -30°F to +230°F/-34°C to +110°C. May be specified for cold and hot water service within the specified temperature range plus a variety of dilute acids, oil free air and many chemical services. UL Classified in accordance with ANSI/NSF 61 for cold +73°F/+23°C and hot +180°F/+82°C potable water service and ANSI/NSF 372. NOT COMPATIBLE FOR PETROLEUM SERVICES OR STEAM SERVICES
