Gruvlok 4-inch EPDM gasket for plumbing systems

This Gruvlok gasket is a Grade EP sealing component made from EPDM material and sized at 4 inches. It is designed for use with manufacturer numbers 390003085 and 390013548 in piping installations. The product carries ASTM D2000 compliance and NSF certification for water system suitability. It is not intended for buyers who require a different pipe diameter or a non-EPDM material grade.

Temperature-rated build for water

The EPDM construction operates across a range of -40 to 250 degrees F, maintaining seal integrity in both freezing and hot-water conditions. NSF certification confirms the material meets health-effect standards for potable water contact. The gasket fits the specified Gruvlok fittings directly, so installers can assemble joints without adapting mismatched hardware. It does not suit applications that exceed the stated temperature limits or require a different compliance standard.
