Uses & Compatibility
The LockNLube® Grease Coupler XL, just like the shorter original, 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. Guaranteed.
The XL is suited for all machines, but especially useful for U-Joints, Harvester Heads, shielded PTO shafts, and any fittings buried deep behind a shield. With almost 4" 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. Watch our YouTube video demonstrating the LockNLube® Grease Coupler XL.
Product Features
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 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.
Replaceable Seal & Jaws
The LockNLube® Grease Coupler XL is fully rebuildable. If it starts to leak, you simply replace the seal and jaws and it is as good as new. See our tutorial here. We include a free replacement seal and jaws with every coupler that we sell. Additional Seal Kits are also available from our store. The seal kits for the LockNLube® Grease Coupler and the LockNLube® Grease Coupler XL are identical and can be used in either model.

The LockNLube® Grease Coupler XL features almost 4″ of reach, 2″ more than the standard LockNLube® Grease Coupler. Especially suited for deeply recessed fittings, and with the same leak-free, hands-free convenience of the traditional model.

Works very good !
I recently purchased a rear blade for my tractor and found that all the grease fittings were recessed about 2 inches deep inside the frame of the blade. I could get my old grease coupler on the fitting but removing the coupler from it was almost impossible. LockNLube Grease Coupler XL was an answer to my prayers and truly made my life easier. Thanks again.
Works just fine. Pleased with the quality and functionality. Made the job a lot easier.
very good to deal with
