For husband.

This little gadget seems to work very well. I have used it only a few times so far, but it clamps on easily and holds firmly.

Fantastic product. Makes a tight seal, no leaks, no mess. Grease goes where it should and not in your garage floor or yourself. Easy to attach to any standard grease gun. Attached mine to an 8 inch flex hose to get into hard to reach places. Its pricey but with every penny.

works perfect. Pretty neat how it actually works. Easy to get on and off the zerk.

I should’ve bought this year’s ago! Works great

Best invention ever. Which I had picked one up Sooner

Depending on the zerk fitting size depends on how tight it attaches. I had a few zerk fittings that leaked on top of the zerk. But for the most part it worked well and saved me from needing two hands.. I like. Make sure you clean your zerks to get the best tight fit. I would recommend getting one.

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

Just squeeze, clip it, and pump the grease. Took a 7min job down to 3min. I only had one issue with an off angle grab where it slowly wept a little out around the jaws, but I didnt notice until I went to unclamp it from the driveshafts grease zirc.

Should have got one years ago!
