GREEN LINE HOSE & FITTINGS G1616V-200X4 2" VIC NIPPLE TO NPT THREAD

Grooved pipe couplings are used to join pipes after grooves have been applied with a roll-grooving machine. 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 pipe 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 inch Hg. Other gasket materials are available on special request.
