LockNLube® Grease Gun Coupler
End greasing frustration with the LockNLube® Grease Coupler—the ultimate solution for leak-free greasing. Compatible with all grease guns and grease fittings, it locks on, stays on, and won't pop off under pressure. That means less mess, and less wasted grease.
With its unique sliding sleeve and thumb lever, the LockNLube® Grease Coupler easily locks its four steel jaws onto the Zerk fitting, creating a secure, leak-proof seal. And when you’re done, a simple press of the thumb lever releases the coupler—even under pressure. The perfect solution to greasing recessed fittings that make removing your coupler a zero-breaking chore.
The LockNLube® Grease Coupler is fully rebuildable. If it ever starts to leak, just replace the seal and jaws, and it’s as good as new.
It works with all major grease gun brands—Lincoln, Milwaukee, DeWalt, John Deere, Alemite, Pleas, Legacy, and many more—so you know it’s the right fit for your tools.

Not sure yet but I think I should have got the long one
Had trouble with first one but I think it was due to weakness in my hands. Due to nerve damage.. Thay sent another one that works better. still leaks a small amount around the zerk but way way less than the old tip I had. Overall would buy again. Maby the long one.
It does what I hoped it would
Attaching this coupler to my grease gun was simple and quick. I have hard to reach fittings on my tractor that have caused a lot of frustration trying to grease. As soon as I put this item on my grease gun, I tried it on the worst fitting I have. It was simple to use, didn't pop off during use, no leaks, no mess, released easy when I was done and didn't leave a mess on the fitting. I was so pleased I greased a few other items in the garage. This coupler is well made, easy to use and does the job. I recommend it to anyone that has grease fittings in odd places. I'm happy with this product.
GREASE GUN COUPLER WORKS GREAT.
The Lock/n/lube grease coupler works great. It gets a firm grip. A great asset in my job.
Excellent product
It is everything you described in your video. I love this product. I'm changing all my grease guns over to this coupler.
