The LockNLube grease gun couplers are compatible with all grease guns and grease fittings and 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. That means you'll have both hands free to operate your grease gun and know that the grease will go in, not on, your machine. End greasing frustration with LockNLube grease gun couplers!

Product features:

* Unique sliding sleeve, activated by a thumb lever
* Sleeve locks the four spring-steel jaws onto the Zerk fitting and releases the jaws by pushing on the thumb 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
* The LockNLube grease coupler is fully rebuildable—if by chance coupler starts to leak, simply replace the seal and jaws, and it will be as good as new (LockNLube includes a free rebuild kit with every coupler that they sell) and additional rebuild kits are also available
* Works with all grease gun manufacturers, including Lumax, Alemite, Plews lubrication (Edelman), Granger, SKF, Macnaught, ADT, Milwaukee, John Deere, Wilmar, Legacy, Allstar, Sealey, Draper and many others
