3" (76.2 mm) Rigid Grooved Coupling forms a water-tight seal between two grooved pipes in fire sprinkler systems, standpipe systems, plumbing, HVAC, and water-based systems. Pipes joined by rigid grooved couplings behave like flanged or welded pipe, but can be installed significantly faster.
This UL and FM-approved 3" (76.2 mm) Rigid Grooved Coupling features a ductile iron body conforming to ASTM A536 Grade 65-45-12. The gasket is made from EPDM synthetic rubber, recognized as the most water-resistant rubber on the market today. Two pairs of carbon steel M12x60 nuts and bolts facilitate quick installation.
3" (76.2 mm) Rigid Grooved Coupling features built-in teeth that firmly grasp the pipe ends, facilitating straight pipe lays over short and long distances. Rigid couplings allow less than one degree of deviation from a straight line (angular deflection. This coupling offers a maximum working pressure of 500 PSI (3.4 KPa) depending on pipe diameter and thickness.
