The couplings provide severity for internal pressure applications. They are designed for fire protection.
It provides a restrained connection that combats various types of loads.
Rigid Coupling housing are made up of ductile iron confirming to ASTM A536 and the rubber gaskets are made by EPDM with rated working pressure up to 500 psi.
They feature high pressure ratings.
Rigid Grooved Coupling features higher working pressures up to 52 Bar/ 750 PSI.
Rigid Coupling provides better rigid connections for valves, fire mains, long straight runs etc.
