GROOVED PIPE COUPLINGS

Pipe Max. Working

Grooved pipe couplings are used to join pipes after grooves have been applied with a roll-grooving machine such as a RIDGID 918. When installing couplings always lubricate the gasket exterior and lip as well as the inside of the coupling to avoid pinching the gasket. Stretch the gasket over the pipe ends then place the coupling segments over the gasket and fasten the nuts and bolts. Tighten until there is metal to metal contact on the bolt pads, then tighten another 1 ⁄ 4 to 1 ⁄ 2 turn. CRN numbers for grooved fittings are available on request. Maximum working pressures are based on a 3:1 safety factor, but may be affected by pipe wall thickness, material, and type of groove. Grooved couplings are suitable for vacuum service up to 10” Hg Other gasket materials are available. For grooved pipe assembly lubricant see G38-GL2 Groove Lube in the accessories section at the end of this catalog.

For HDPE pipe coupling applications. Please note, since the working pressure of G38HDPE is much greater than HDPE pipe, working pressures of the system are governed by the pipe and can vary based on composition, wall thickness and service temperatures.
