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.

United StatesI tried other locking heads with poor result, this one worked as advertised. My boat trailer has hammer in fittings and would pull out with regular grease guns. With the LockNLube, I clamp it on, pump in grease, unlatch and remove my grease gun. My Problem is solved!
United StatesI absolutely love this product. A few years ago I got my dad a Dewalt 20v grease gun this LockNLube attachment has made the setup invaluable. It has made greasing tractors and equipment and mowers and just everything so much easier. Thanks for a great product.
United StatesGreat. I put it on my Milwaukee battery grease gun. Great fit, fast , easy to handle and no mess.
United StatesGreat product and locks on great
United StatesWorks better than expected
