Pour pouvoir graisser avec les mains libres, très efficace.

I bought this to grease my tractor, tiller, auger, vehicles. I have been using this for two years and it works great. Great company.

When you look at it, you think how does this work? But after using it since the jaws retract inside the outer hub makes it easy to get on harder to see zerts. And it really locks on, like this better than the ones where the jaws come out in front of hub. I would recommend this product!

It works really well, grabs onto the grease fitting and doesn't leak.The end is to large to fit some of the loader fittings on my tractor

Attaches securely to grease nipple does kit pop off when pumping. Fixes stuck fittings
