Grease Gun Coupler: 6 Jaws Securely Lock onto Zerk Fittings, Leak-Proof Design, Handles 10000 PSI Quick Release Grease, Compatible with All 1/8" NPT Grease Gun Couplers.

I'm embarrassed to admit how long I've struggled with grease guns. Too often it was impossible to get a good seal on the zerc and then difficult (or impossible) to get it to release. After such a recent failure I went shopping. Finally ordered this product. This thing is amazing. Simple and easy to connect to the fitting. No strain at all. And then disconnecting is ridiculously easy. A child could do this. I've only used a couple of times, but so far I'd recommend to anyone.

What can I say, it's way better than what my grease gun came with.

Cheap price and works great for my tractor. You won't regret it.

Some of these couplers are better, this one gives me a hard time, hopefully it will be better after a little use - not as bad as trying to remove the standard coupler if you get pressure on it, or it won't clamp tight and just makes a mess - good in most cases

I have tried others that do not work as advertised. This one fulfills all my expectations.

Works great!

Good design, easy to use, but it failed on the first use. I have a fitting that was a bit hard taking grease, needing a little higher pressure than normal, and it wouldn't stay attached. I even tried changing the fitting, but no luck. I ended up going with the name-brand one that is more expensive... The one that you're able to Lock on and Lube with.

Perfect fi easy on , worked great...
