Grooved pipe fittings consists of grooved couplings, grooved fittings, grooved outlets, grooved valves and grooved replacement parts. Typical application of grooved fittings is in sprinkler risers, pipe feeds passing from one building area to another, locations prone to earthquakes, in discharge line above pump suction, in air or water fire services lines, piping system subject to excessive vibration, installation in tight spaces or where pipe alignment is difficult.
Grooved pipe fittings are limited to use with rolled or cut groove pipe, valve and fittings. These fittings are rated to 175 psi (1205 kPa) as a minimum. Pipe grooves are made according to ANSI/AWWA C606 specification "Grooved and Shouldered Joints".
These couplings are FM approved and can be used in underground services. The maximum ambient temperature for these couplings are 225 deg F (107 deg C)
These couplings are sold by nominal pipe sizes and will fit the corresponding nominal pipes, valves and fittings.
