Great item. Will never miss it

This works great for getting grease into the fittings. Not around.

just what i wanted

easy to use and quick ship.

Well, its more like Lock N Wiggle Wiggle Wiggle N Lube. You have to wiggle it around a little bit to get it to seat and seal. Works great after that. Love that i can get two hands on the gun for those stubborn zerks.

works as advertised!!

clamp it on start pumping gun with both hands it stays on.

Great addition to a grease gun. A must have!!

This works so much better and faster than the screw kind you usually have on the grease gun. I kept the original just in case I need it since this requires a little more clearance but I hope to never have to mess with that.

Worth every penny. Your days of getting frustrated are over! I used to get so mad when I couldn’t get my grease gun unstuck off of the zerk, but not anymore! This product is frican incredible. I got all my zerks greased in a fraction of the time that it used to take. Easy to use and the best part is my hands aren’t all cut up from fighting the stuck grease gun! Must have!
