Screw-On Relief Valve Coupler

This handy screw-on style coupler includes a built-in needle valve for isolating the hose assembly from a leaking check valve in the body grease fitting.

Commonly used for wellhead valve maintenance. This screw-on coupler combines a one-way check valve and a release tool. Ideal for servicing wellhead gate valves, quickly and easily.

In the event that an old or inferior fitting fails during service the coupler can safely be left on until the next scheduled shut-down. Keep a few extra couplers in your kit for this reason. Available in carbon steel ONLY.
