LockNLube Grease Gun Coupler locks onto Zerk fittings. Grease goes in, not on the machine. Worlds best-selling original locking grease coupler. Rated 10,000 PSI. Long-lasting rebuildable tool.

The thing just works. I was finally able to grease a gate that I haven’t been able to do in 3 years. It locks on so all the grease goes where it is meant to go. Only con I have wish it was a bit cheaper but it’s well worth the money.

I cant believe I even questioned buying this. Hands down the best tool in the toolbox. grease guns are useless without this. Makes greasing my Kubota a breeze. I should have bought 3 and given them to friends.

I dont know why I had not purchased before, I saw these on a TV Mechanic show and was sold. I have to lube my jeep and Boat trailer regularly and these make it a snap... They click on easily HOLD tight and release easily without tugging and pulling. Especially no grease fitting breakage. If you have ever broken one and then spent the next hour fixing it. You know these fittings are worth it....

First time I was able to grease a fitting and it not getting stuck Buy it and will not be disappointed

Bought this to put on my grease gun to grease my Can Am X3 grease zerks. Works like advertised. Grease gies in fitting and not on machine. Highly recommend.

For decades I have been dealing with grease all over everything, and having to use a pry bar to remove my grease gun from the grease nipple. This little tool works Great!

Been wanting one of these for a couple of years, but always thought 30 bucks was a bit much. I finally relented and bought one.....simply fantastic is all I can say!! I should have done it years ago!!

very good

Just used today for total lubrication of Cat D5 Dozer. Grips tightly, not leaks, easy to remove under pressure. Took less time to grease machine than normal. Should have bought this a long time age. Highly recommend.

Best grease gun tip replacement, keeps everything clean and never falls off
