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 bought this for my husband and he finally go the chance to use it and said it works better than any other grease gun that he has every used. Its definitely worth the asking price!

Locks onto my zerk adapter and works great.

So far so good, might need angle attachment if available.

This thing is great! Easy to change out with my original grease gun fitting. Less than 2 minutes or so. Easy on and easy off the zerk fittings, its fantastic! No more loosing my religion when trying to disconnect from the fittings. Is it worth the price? Absolutely!

Perfect. Now the grease goes into the fitting and not on me. Love this thing.

Love this coupler! Works great and prevents the risk of breaking grease zerks.

Works great I do a lot of greasing . Own a lawn service . I have it on my bucket of grease

I had trouble with a zert on my brush cutter shaft taking grease. No problem any more. I will oder more of them

Awesome product. Original head kept getting stuck on the fittings. This one goes on easy and holds tight until you are ready to separate. Well made and even came with extra parts for rebuilding. Must have!

This thing is a miracle. Always hate greasing because it pops off and gets grease everywhere. This thing just locks on, grease, and done. Simple to use.
