2 in. (50.8 mm) Red Rubber 150 LB Ring fits ASME/ANSI Class 150 flanges used in industrial piping, commercial plumbing, and fire protection systems. This red gasket is sized for pipes with a 2 in. (50.8 mm) nominal pipe size and installs in flanges used to form a water-tight seal between pipes and fittings in flanged fire sprinkler and standpipe systems.
This 2 in. (50.8 mm) Red Rubber Ring requires less material and less cutting than full-face gaskets and can be installed without completely unbolting the flanges.
