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.

After 2 of my favorite YouTubers highly recommended LockNLube, I had to try it. Just installed it on my Milwaukee cordless grease gun, Im a believer. Thanks to Outdoors with the Morgans and Wranglerstar for recommending this product.

Works great. I hope it lasts a long time

We had to reduce our maintenance cost on our vehicles. The $100.00 oil changes had to end. The magic combination is an air pressure grease gun, a 34” grease hose and this quick release connection. Lost a one handed operation. Great product.

Perfect addition to my grease gun -

works well but would be easier if the release were longer

This product is great, I have 2 of them, one for the shop and one I keep on my fifth wheel. Recommend to everyone. Well worth the price. Awesome product.

The lube fitting works great. I do a lot of greasing as I have commercial mowers and a Large stump grinder and each has many hard to get to fittings. This fitting has really made my job much easier. The fitting is well made and durable. I have yet to find anything bad or wrong with this fitting and if used properly should give anyone long life. I grease over 40 fittings a day.

The item was received in good condition within the expected delivery window.

This grease tip is a game changer! Don’t think twice but one. I bought my first one 4 years ago and still works awesome. Mine came with orings to rebuild and haven’t needed to. I do a lot of greasing and this makes it so easy. You’ll pay for it three times but not having to buy those crap Lincoln tips that only last a week

Works great! Fits like a glove and makes life easier.
