LockNLube XL Grease Gun Couplers

The LockNLube XL grease gun couplers are well suited for all machines, but especially useful for U-Joints, Harvester Heads, shielded PTO shafts, and any fittings buried deep behind a shield. Just like the shorter original version, the XL couplers are compatible with all grease guns and grease fittings. The coupler 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. With the LockNLube XL grease gun couplers almost 4 in. of reach, you can be confident that you'll reach your fittings and grease will go in, not on, your machine. When you want to release the coupler, simply depress the thumb lever, even at extreme pressures.

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 is as good as new (LockNLube includes a free rebuild kit with every coupler that they sell) and additional rebuild kits are also available
