The Flange allows direct connection of Class 125 or Class 150 flanged components to a grooved piping system.

The two interlocking halves of the 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.

All 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 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.
