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.

Best lube gun I’ve owned.

This product is a dream come true works Great and I would recommend this to every one who has to grease anything will not come off until you want it to have several friends that have ordered at my recommendation.

Must have for all grease guns. This works perfectly on my 20v dewalt. If your in the market for one of these buy it. I use this multiple times a week and put anywhere from 8-10 tubes a week. Works awesome. Stays on fittings perfectly. Also a nice plus is the rebuild kit that it includes.

This little tool makes greasing my zero turn mower easy. Its easy to snap on the fitting and I dont waste grease. Its worth the price.

Only used it once so far.

Snaps right on and off with no mess. No leaks. Distributed grease in stubborn fittings. Cleanest Ive ever been after greasing my excavator.

Got tired of busting mu knuckles pulling the old fitting off the grease zerk. This works well even in recessed areas on the tractor loader. I think it is a little over priced for what it is but I bought it anyway. No regrets.

Works fine. Ive had a limited opportunity to use the item but it performed as advertised on the 4 fittings Ive used it on so far.

My new position at work requires me to do a considerable amount of greasing motors and pumps. This item has made my job 100% easier and more productive! Awesome addition to any tool box! I highly recommend this to anyone who uses a grease gun

Really like this attachment. Frees up your hand while using the grease gun. It locked on the zerker fitting perfectly.
