G.Coupler – The Original Professional Self-Locking Grease Head for Zerk Attachments – Easy to Fix and Remove (M10 x 1)

Works perfect and doesn't leak where standard ones do and can get them in blind holes aswell.

Tried a few cheaper ones and none lasted more than a week! I've been using this almost daily for a few months and still working like new. Definitely worth the extra expense over cheaper copies

Works well.

Great product. Just serviced 5 artic trailers all with drum brakes so lots of grease nipples only failed on 1and that was because it was damaged. Would highly recommend this product to diy mechanic right up to professional technician.

We use these for Greasing Agricultural machinery and Implements they always lock on even on a grease nipple that hasn’t seen any Grease for a day or 365days it makes greasing a pleasure rather than a messy chore, it doesn’t leak and always have those ones that once you get it on you can’t get it off. Not with the G. Coupler press the release lever and off it comes. I have 3 of these and highly recommend Them to anyone. Save you time money Grease and patience.

Excellent product, highly recommend.

At last a grease gun nipple coupler that you don't have to force on to or pull off the nipple. No more snapped nipples! Really great product.
