Get grease into machines more effectively and neatly with this 10,000 PSI grease coupler!

This Gun patented pressure return valve, takes 10,000 PSI from a 10-foot hose and returns it to the canister with no mess. The pressure drops to 0 PSI in an instant and gets off easily to avoid leaks and mess when dealing with clogged fittings.
The unique Grease Coupler is compatible with all grease guns and grease fittings. It does not leak once locked on and will not pop off under pressure. No hands are needed to align or hold the coupler in place while greasing. You have both hands free to operate your grease gun and know that the grease will go in, not on, your machine. 
It has a unique sliding sleeve, activated by a thumb lever. The sleeve locks the four spring-steel jaws onto the Zerk fitting and releases the jaws by pushing on the lever. When the jaws are locked onto the Zerk, a leak-proof seal is created. The locked connection is positive and rigid preventing the coupler from coming loose and breaking the leak-proof seal. If a fitting becomes pressurized, especially a recessed one, just depress the thumb lever and release the coupler.

Hardened steel spring-loaded grease coupler with a lock on jaws is designed to withstand breakage, leakage and warping up to 10,000 psi (690 bar). 1/8” NPT fitting can lock on to all SAE and Metric Zerk grease coupler fittings with all grease gun types - manual, electric, air and bucket greasers.

Package Includes: 1 x Lock Grease Coupler
