Makes ease of greasing in tight spaces a breeze

This thing is great.wish I had found this years ago.get a long handled grease gun and save you hands from hurting from having to pump with one hand.

Could not be happier. Product works fantastic!

I like it seems to lock in nice which results in less mess

I was using a competitors product that was supposed to lock onto grease zerks, but often wouldnt and the design was too fat that I couldnt reach recessed zerks. I ordered one of these and changed it out on my Dewalt grease gun. Holy cow! There were zerks that I kept passing during maintenance because the grease would go everywhere, but inside the zerk. Immediately I heard popping and cracking, the sound of grease making its way in surfaces that havent seen grease in some time. I also like that it keeps a very fine bead of grease, not just goops and globs like other heads. You waste less grease by getting into the zerk and on the surfaces, not on your hands, you clothes, and all over your tractor. I actually look forward to every 10 hours when I lube my front end loader as its such a breeze with the LockNLube coupler.

This is my second purchase of this item. It works great and locks on perfectly for a positive contact. No grease spits out the sides. Highly recommended.

Works great

Put in on my mini-grease gun and greased my auger on the snow blower. Worked great. Grease went into nipples on the auger easily when the coupler was attached. Love it!

Exactly as expected

Im surprised this thing really does work well. I use it on large construction cranes sometimes hitting 10-15 fittings in a row its never came off a fitting yet. Really a nice ad for a power grease gun I bought the Dewalt 20 V which is awesome look into it!
