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.

Works great and saves grease and frustration. A quality product at a reasonable price.

I have several tractors on my property. All of them need to be greased often to keep them up and running smoothly. My old grease gun came with a standard coupler, but honestly, never worked well and you could not get into tight places. This coupler has a much smaller diameter which allows you to get into tight places. I am sure all tractor manufacturers place their fittings in the worst possible place 😂. The coupler locks on tight, which is important for fitting that are slightly frozen and stiff. You must be able to push the ball down in the fitting to get the grease in. Price and value are very good.

I would give 5 stars if both fittings worked. Two are provided but one leaked grease all over the first use. However, the second one works fantastic. I have a 2017 model Branson Tractor that has never properly connected and/or released other grease couplers correctly and easily, and I've tried many. This is the first and only one to work perfect connecting and disconnecting from all fittings. Wish I'd had it the past 8 years. It's awesome!

I have a grease gun from harbor freight. From the first time I used it, it would not release nomatter what! I had to take it apart for each use. I got these and just plugged the tube and end into the harbor freight grease gun and bam! It works perfect! I have filled several trailer wheel hubs and more. So nice!!! Grabs and releases no problem.

These fittings are nice for cars and trucks or for heavy equipment. I own 22 tractors and lock on fittings do not work on tractors with off set fittings. To long. They do work on my trucks. So if you have off set fittings they will not work.

Easy to use and worked perfectly

Es práctico sencillo de usar ahorras tiempo, yo engraso una máquina y me tardaba una hora 45 minutos en engrasarla, pero ahora con este tipo de engrasador se ahorra demasiado tiempo, sólo lo conectas y está listo, no te tira, no se desconecta y evitas esfuerzo de estar sosteniendo y tirando la grasa, lo recomiendo al 100%

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 have tried a few different kinds of grease gun hoses and connectors, and this one is decent. It is a quick and easy upgrade to your grease gun, making operation a lot more predictable.

Bought this for my husband he was very satisfied with it. A good price and it came quick.

I was worried when ordered it would be to large to fit in some places but it is no thicker than old tip.nice locking mechanism. Delivered quickly.
