HOW IT WORKS

3 EASY STEPS TO GREASE ANY MACHINE

1. Use thumb lever to open jaws and attach to Zerk fitting.

2. Experience greasing with no leaks and both hands free to operate the grease gun.

3. Push down the thumb lever to easily release from the grease fitting.

FEATURES & BENEFITS

DESIGNED FOR RECESSED AND TIGHT GREASE FITTINGS

The patented locking mechanism allows you to easily attach and detach the coupler using a thumb lever. No more fighting to get the coupler to release from a Zerk down in a hole or tight space, just push the thumb lever and it pulls right off. The outer diameter of the LockNLube Grease Coupler is the same as four-jaw couplers. The diameter of the working end of the LockNLube Grease Coupler is 5/8" - nearly identical to heavy-duty standard couplers.

Extensions, needles, 90-degree adapters are all available to buy (or build with spare parts from your shop). See the complete list here.

Has a lower liftime cost than any grease coupler in the world

LockNLube Grease Coupler is the world's only rebuildable coupler. Our seal and jaws are long-lasting and when they do wear out, you can simply replace them rather than buy a new coupler. We include a free spare with every coupler, and new one can be purchased for $7.85, less than the cost of a disposable traditional coupler.

Will not pop off or leak under pressure

The LockNLube Grease Coupler is rated to 10,000 PSI (690 Bar) and will not release under pressure. No hands are needed to align the coupler or keep it attached. No leaking grease, and no problem using both hands to pump your grease gun, or move around the machine. Eliminate frustration from machine maintenance by using the only grease coupler that is guaranteed not to leak and not to pop off under pressure.

REVIEWS FROM OUR CUSTOMERS

"Best investment I've made, makes maintenance a lot easier when you don't have to strain, twist and stretch to hold the coupler on the fitting!"

Grady H.

"I will say this makes using a grease gun very easy!! Anyone that has used grease guns with the press on fitting knows how aggravating it can be to get off the grease fitting. This addition is very easy to install and use. Everyone with a grease gun needs one!!!"

Timothy W.

"Excellent. All the years struggling with difficult grease zerts and now the grease goes in the fitting not all over the machine. Awesome solution to get grease to go in the fitting."
