Uses & Compatibility
The LockNLubeĀ® 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 LockNLubeĀ® 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 LockNLubeĀ® 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 rebuild kit with every coupler that we sell. Additional rebuild kits are also available from our store. The rebuild kits for the LockNLubeĀ® Grease Coupler and the LockNLubeĀ® Grease Coupler XL are identical and can be used in either model.
LockNLubeĀ® Grease Coupler Care & Maintenance:
Check out our YouTube channel for an easy method to clean dirt and grit out of your coupler. This will extend the life of the seal, which means longer use time between rebuilds. If you find your coupler starting to leak, try this cost-saving tip before you put a rebuild kit in it.
Consider using a Coupler Cap and Zerk Fitting Caps to keep your equipment clean.

Excellent worked as it was supposed to
Jason Lawson
This is the best grease coupler I have ever used by far!! Love it and will be buying more soon for my entire company.
As advertised
The last locking coupler I had was too big in diameter to fit in the holes to reach the recessed fittings. This one does the trick.
Great Product and Great Customer Service!
I'm very happy with the couplers! They seem very well built and work well. The customer service was excellent! The first order arrived and the package was empty (it appeared to have been opened and the couplers removed!) I called LockNLube customer service they immediately sent me replacements with no hassle.
Just what I needed!
