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.

Is as expensive as a whole grease gun but worth every penny. It also comes with an extra jaw set that increases the economy and extended use of the device. It is very easy to use and wonder how I lived without this. It saves so much time, and even at an angle it does not leak grease, no pressure required or slipping off.

Made lubing them zerks on a driveshaft muchh easier to connet and disconnect.

I added this to my Dewalt 20v cordless grease gun. (Cordless grease gun definitely worth the money if you need to grease equipment daily) Im sure it will work well on any grease gun. It makes it much easier to connect and disconnect to grease fitting.

Worth a couple dollars more . Works better than the others . And its rebiuldable

No more spilled grease!

Im very impressed so far, I havent had the chance to use it extensively, but the few times I tried it has worked better than I expected. Im using less grease and Im not wasting time cleaning the mess that the conventional fitting left.

Bought this used it LOVE IT !!!! Way better than my old tip! This is a must have. Some cramped spaces may be an issue. Haven’t had that problem. Love the tool this thing fits snug on the fitting letting you have the freedom of not having to hold the tip flush by hand and squirt grease everywhere

My Kubota has a number of grease fittings with limited access, where a regular grease gun will go on, but cannot achieve the angle to remove. This coupler is a game changer as it can be removed without changing the angle of the grease gun. Expensive for sure, but when you factor in the time not spent changing broken grease fittings it becomes a valued investment.

Just what I wanted.

I got tired of fighting the standard fitting...this is soooo easy to use. The biggest issue is you have to have straight access to the fitting, and sometimes this is tough on some tractor fittings.
