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.

We have a bit of farm equipment that always needs greasing and my husband found this online and wanted to give this a shot. He said it works perfect! He is very impressed.

Used on my mower in the out of reach places. Worked great. Attaching and removal was a breeze .Easiest time I’ve ever had doing the task. Also used an extension hose from Amazon.

Nice and easy to remove

This device is a must-have for anyone using a grease gun. I recently had to grease a Zerk fitting on a tractor, and the guns nozzle was stuck on so tightly that I had to pry it off using a crowbar. The LockNLube detached easily from the same fitting. This is a 5-star item; essential for greasing things. However, there are two improvements for my usage. The device should be able to swivel; otherwise you may have to go through some gyrations in order to position your grease gun. Secondly I find that some of my Zerks are in locations where the LockNLube is just too long to fit in. Perhaps a right-angle joint will help.

Both of the products that I ordered work better than I expected them to. The needle nose fits right into the grease gun coupler. The grease gun coupler grabs the grease Zirk and no leaks. What a concept!

A little spendy but you won’t but a different one after works great and does what it should very happy

Much easier greasing, better seal, less mess.

It is a little aggravating to use. It wont really get into tight places. It doesnt seem to seal any better than a regular grease tip. It gets stuck on some grease fittings. I used it once and put a regular grease tip on.

I own a few 4x4 trucks and tractors they all require to be lube every once in a while. But if your grease gun don’t have this tip it’s been hard to get the normal tip of a grease gun off with out breaking the nip off. This is one of the best investment I done on the property. It have greasing any equipment easier and strong to deal with.

Spend the money, its worth every penny to make greasing fittings simple one handed.
