Details
End greasing frustration with the LockNLube® Grease Coupler. It is the ultimate solution for leak-free greasing. Compatible with all grease guns and grease fittings, it locks on, stays on, and will not pop off under pressure. That means less mess and less wasted grease.
With its sliding sleeve and thumb lever, the coupler locks four steel jaws onto the Zerk to create a secure, leak-proof seal. When you are done, press the thumb lever to release the coupler, even under pressure. It is the perfect solution for recessed fittings where removing a coupler can be a Zerk-breaking chore.
The LockNLube® Grease Coupler is fully rebuildable. If it ever starts to leak, replace the seal and jaws and it is as good as new. It works with all major grease gun brands, including Lincoln, Milwaukee, DeWalt, John Deere, Alemite, Plews, Legacy, and many more.
