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.

Easily connects and disconnects on a grease fitting. Very nice not to have to twist, bend and pull to remove form a fitting. Just press the lever and release with very little pull. Very helpful in tight places.

works great only used once grease tractor and brush hog. to me its a little pricey, will see how it holds up.

Makes life easy.

Makes greasing so much easier. there are a couple of points I have to use a grease needle on and this helps with that also. i used to always get a handful of grease trying to hold it in the hose coupling. now it locks in and i can focus on getting the needle tip where it needs to be. It even came with parts to rebuild it if I wear it out. I dont use one enough to wear one out though.

Its about 10.00 into my feels but its definitely the tip Ive waited 40 years for. No more ripping drive in zerks out.

Works perfect, no mess, even great on stuck grease fittings.

I was a bit apprehensive when I purchased this coupler but I like it. I would

It must have for greasing. This cuts the time of greasing in half and do not have zerk fitting blow outs!

I’ve only used it to grease 4 fittings so far, but they were on my suspension and a pain to get at, let alone hold the head on with one hand and try to pump the gun with one hand. Excellent product. I got one for my father in law as well. If you have farm machinery and you don’t have one of these, you are missing out. Not sure how long they will hold up, but it does come with additional seals. At any rate, if it fails next month it’s still worth it to me to not have to contort my left arm into a small space and try to pump grease into a tight fitting with one hand.

It is clearly superior to the screw on type grease gun connectors. Yes, its a little pricey, but well worth the money. Makes greasing zerks SO MUCH easier!
