Fig. 7013
Gruvlok Flanges (#300 Flange)
The Gruvlok Fig. 7013 300# Flange allows direct connection of
Class 250 or Class 300 fanged components to a Gruvlok
piping system. The two halves of the 2" thru 12" sizes of both
Gruvlok Flanges are drawn together by a latch bolt which eases
assembly on the pipe. A specially designed gasket provides a
leak-tight seal on both the pipe and the mating fange face.
Gruvlok Flanges have designed-in anti-rotation tines which
bite into and grip the side of the pipe groove to provide a
secure, rigid connection.
Gruvlok fange adapter insert required when mating to rubber
surfaces or serrated faced mating fanges.
