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.

i like it but you have to squeeze the lever a little to much but other than that its great

I thought it might be just hype until I tried it. The Lock N Lube connects and stays connected until you take it off. No popping off before the job is done like the ends of other products. I would highly recommend this for anyone that uses a grease gun. Great product in my opinion.

Works great. I hope it lasts a long time

Wish I had one years ago! Works very well. Well worth the money.

this hangs on to the fitting for two hand operation of the gun. works great

Bought this greasing zerks on my little lawn tractor. Tough places and hard to disconnect without scraping your hands/fingers. This is way easier and worth the money. Worked well, on one of the zerks I did have to wiggle the LocknLube to get it seal to the zerk. But it worked just fine and released clean. Good stuff. I enjoy the accomplishment of keeping equip with fresh oil and well-greased, and now its way more enjoyable!

He had to grease the tractor and attachments. Apparently this gets the job done, even in stubborn areas.

So easy to clamp on and off with no leaks!

Better than chrome on a paperclip. Hope the inventer gets rich. Maybe he/she will come up with another superlative idea.

If you work with heavy equipment youll know how tough it can be to get grease into stubborn fittings. I havent had one refuse grease yet.
