Grease Gun Coupler 12000 PSI Heavy Duty with Quick Release - 0.53" Tip, Secure Lock, Universal Fit for All 1/8" NPT Grease Guns

I like using this because I don't need a third hand to hold it on the fitting. It clamps on and stays in place, and it allows me to save time.

Locks on like it should and doesn't leak while greasing fittings

This little thing is a game-changer for sure! No one wants to be under a truck in the first place, but this speeds things up in a big way. It snaps right on to standard-sized grease zerks and gets better with age (a little stiff for the first several uses).

This THINKWORK Grease Gun Coupler was just what I needed!! I kept trying to put grease in my Pontoon boat trailer wheel bearings, but grease just kept coming from the grease jerks making a mess %26 wasting grease!!!! I installed the THINKWORK Grease Gun Coupler on my grease gun %26 like magic I was actually putting grease in the wheel bearings. Water was actually coming from the bearings.

fit perfect. works great

The Thinkwork grease coupler was easy to install. Easy to attach and remove to and from the grease fittings. Holds tightly to the fittings. I've ordered another coupler for my daughter tractor.

had problems using the fitting in tight places but other than that if you had a large area the work with it was very useful

lever that pulls back spring clamp constantly comes out of slot. will not hold together. when it srays in place, it works well

I used the unit 1 time and it fell apart.

it broke the first time I used it. the "spring lever" came loose from the "thumb lever" it is junk
