The Gruvlok® FIG 7012 flange allows direct connection of Class 125 or Class 150 flanged components to a grooved piping system. The two interlocking halves of the 2 in thru 12 in sizes of the Gruvlok® flange are hinged for ease of handling, and are drawn together by a latch bolt, which eases assembly on the pipe. Precision machined bolt holes, key and mating surfaces assure concentricity and flatness to provide exact fit-up with flanged, lug, and wafer styles of pipe system equipment. A specially designed gasket provides a leak-tight seal on both the pipe and the mating flange face. The 14 in thru 24 in sizes of the Gruvlok® FIG 7012 flange are cast in four segments. A sleek profile gasket design allows quick and easy assembly of the Gruvlok® flange onto the pipe. All Gruvlok® FIG 7012 Flanges have designed-in anti-rotation tines which bite into and grip the sides of the pipe grooves to provide a secure, rigid connection. The Gruvlok® FIG 7012 Flange requires the use of a steel adapter insert when used against rubber faced surfaces, wafer/lug design valves and serrated or irregular sealing surfaces. In copper systems a phenolic adapter insert is required, in place of the steel adapter insert.
