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.

A chore is now easier to do.

I have 24 grease fittings on my UTV and some of the fittings are located where holding the grease gun on the zero was extremely difficult without making a mess. This tool installed on a flexible hose made the job a lot easier. I received a email with a thank you and instructions on how to properly use the product BEFORE it arrived. Customer service like that is unheard of and unfortunately unexpected in this new norm. As a machinist of 30 plus years I have found out that quality products and service come with a price! Worth every cent this was!

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

Works great

This tool is great if you use a hose end grease gun. It is often difficult to keep a hose end grease gun coupler tight on a zerk and this tool solves that problem. It grabs the zerk and seats itself nicely and there is no leakage of grease at all. It is a bit larger and makes it harder to get in tight areas but for most applications it is great.

An absolute must for greasing any equipment. No need to keep the hose on straight or else grease goes everywhere. You just clip this on and you can move the grease gun all around and grease will only go into the fitting. Allows for easy one hand operation and allows you to watch the bushings so you know when they are good. I have been greasing machines for 20 plus years and this coupled with a Dewalt power grease gun make greasing a breeze.

Love it. Locks on and orients itself properly, makes tight zerks easy to grease.

All though a bit pricey this product sets my mind at ease that the grease Im pumping is going where it is intended and not making a mess. I could have bought a cheaper grease lock coupler, but the quality was not the same. You get what you paid for. Very satisfied with LockNLube Grease Gun Coupler Lock.

The LockNLube Grease Gun Coupler worked well on most of the grease zerks on my farm equipment. I was not able to use the LockNLube Grease Gun Coupler in areas tucked away in very tight places, for example; a u-joint deep inside of a large shield on a PTO drive shaft. However, I will have to say it did work well and actually cut down the amount of time I spend lubricating all of the tractors and hay equipment since the coupler goes on and comes off easily. Just clip on the LockNLube Grease Gun Coupler and grease, no more twisting the coupler trying to get it to stay on a grease zerk and fighting the coupler to get it back off.

Kind of expensive but got sick of other grease gun ends getting stuck on clogged zerks. So far has worked really great. Kind of big to get into tight areas but works well out on the open
