Grease Gun Coupler 2 PCS, Strong Lock on Greases Gun Couplers, 12000 PSI Quick Release Grease Coupler with 12" Spring Flex Hose, Compatible with All Grease Guns 1/8" NPT Grease Gun Fittings

I would recommend these for anybody that has a battery operated grease gun they work great you attach it. Let go of it and it does not pop off grease does not ooze out on the sides. It locks in the place like it’s supposed to definitely worth the money.

very happy with how sturdy these grease couplers are on how they grab the zerk and never fall off unless you zank it off quite impressed and satisfied with purchase

I've used this once so far... with a trailer wheel bearing repacker. It did the job fine but I used my own rubber hose and not the stiff plastic one that this kit comes with. Anyway it stays securely mounted on the grease fitting and doesn't leak. I would buy it again but since the kit came with 2 it's unlikely I'll need to.

I finally used it today on my backhoe and it was fantastic.. I put it on my new Milwaukee 18 volt grease gun on some dirty old zerk fittings and a locked right on.. I haven't used it long-term but to me it seems really good

Bought this recently to do a dual axle car hauler. Repacked all the bearings with a packer then finished off with the grease gun to fill the hubs. Worked good for the 4 bearing sets that I did. Locked on tight and didn't have any leakage. I almost purchased the name brand one for 2x the price, but figured even if this one only lasted half as long, ide get another and not be out much. Seems to be fairly well built. I like the idea of 6 jaws vs 4 on the name brand one. I didn't need the hose it came with but looks like it would work fine. I notice the name brand one comes with replacement parts so that's kinda sketchy right there. Overall for the $16 this cost at the time I'm pretty happy with it. I have several trailers with ezlube axles and this will come in handy. My old original one always leaked and never locked on tight and was impossible to remove. This one there is a little force required to remove, but nothing I mind and nowhere near the struggle I had with the standard coupler. Overall I would say this is a good buy for the guy that needs to grease something occasionally. Long term, we will see how it holds up but it looks and feels like a decent quality unit so I'm sure it will last me a long time.
