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.

This is great makes greasing so much easier now especially in the hard to reach places

Will never be without one now. Easy to use and no more broken zerks.

Where has this been all my life? Simple operation, cuts my greasing time in half. Clogged zerks? Not anymore... this thing is amazing. If you own any equipment that requires regular greasing, this is a must. If there were an option for 6 stars, Id give it 7.

Like that it is easy to attach to grease Zerks , holds tightly until you release it. Used only a handful of times but pleased so far.

It used to take a hour to grease all the loader points on my Kubota BX, now it is a five minute job.

Nothing to complain!

Neat tool

The best! no more lost grease it forces the grease into the Zirk!!

If your like me you hate messing with getting the grease gun off the zircs! they either break off or you bust your hand on a nearby piece of metal pulling and twisting. This thing is a life saver!

As usual, cant give 5 stars after only using a few times. But I like it so far as I have a long handle type grease gun and this coupler allows for 2 handed pumping. Only ding to the coupler is it is standard size physically so no better access to tight spaces. Maybe so you will buy the needle adapter.
