Saker Grease Gun Coupler-Upgrade to14000 PSI,Duty Quick Release Grease Couplers,Compatible with All Grease Guns 1/8" NPT Fittings(1 PC)

Excellent, does exactly what it is supposed to

Well made, surprisingly heavy with a strong catch. Fitted to a Groz grease gun and works well.

Worked great for a week or 2 but not jaws are worn out and it won't hold onto the grease nipples. Pretty poor really

Tight trigger, strong grip required

Ordered this with a little hesitation because I had some machinery that hadn't been greased for a very long time. I attempted with my regular grease gun, only to find nearly every nipple was blocked and grease simply spewed out of the end of the gun without putting anything through the nipple.On my first use of this Saker grease gun end, all but two out of 8 troublesome grease nipples took grease perfectly. One other nipple simply splayed out to the side, probably a dud nipple. The final tricky nipple just sat there while I piled on heaps of pressure out of the gun. Amazingly despite massive pressure, this did not leak. I am hugely impressed with this product.Just to note that this review is in relation to the smaller end Saker. I believe it is a newer revision of the original. It fitted the recessed nipples just fine.

Bought this for my MAKITA 18v greese gun..fits as it should. The barrel is long for those deep nipples... But used for a few weeks and one of the jaws broke so disappointed with it.

Works well, but one joint was gummed up with hardened grease. The gun just wouldn't pump. Testament to the seal that this product forms at the nipple that no matter how hard I squeezed the gun, there was no leak at the nipple. Hence 5 stars.I'll need to use one of those unblockers to clear the joint out.

Bought one because the allu bucket that’s fitted to the machine wasn’t taking grease. Well it is now !! Simple to use and fit to the grease gun hose. Just click and pump. Less mess and less struggling with the grease nipples and clean hands when I have just greased the whole machine. I’m delighted with it. Was a bit concerned about the size and fitting it onto recessed nipples but so far it’s been perfectly fine on the little 14 ton excavator and fitted on them all. Would recommend.
