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.

Why Didn’t I Buy This Years Ago?
I’m getting up there in years, but still enjoy wrenching. The LockNLube makes greasing my ‘55 Chevy so much easier. Great tool, well worth the cost!
