Almost what I needed.

I bought this to replace the wonky coupler on a Performance Tool grease gun I bought new recently. This item installed easily, and seems to be well made. Now, if you have heavy equipment, or farm equipment, I can see where this would be a major time and aggravation saver. For automotive stuff I would urge caution. It simply will not lock on to the zerks on my u-joints on a 2002 Ford F-150. The coupler is too fat. I will have to remove one of the 12mm bolts on the yoke to be able to lock this on. In other words if your zerk is a straight shot this will work, in a tight spot its width (and longer length than an ordinary coupler) will work against you. I gave it five stars because on ball joints, and tie rod ends its the bomb! For that alone its worth it to me. Some things under a truck are difficult to hold a ordinary coupler and pump the grease gun at the same time, thats where this product shines.

Absolutely worth the price.

Where has this been all my life? Excellent fitting. All grease guns should come with this or similar fitting. It simply works. I thought I was doing something wrong all the years of my life. I could never get grease INSIDE the zerts fittings, always all around the outside. This is worth the expense, take my word for it and thank me later.

Very convenient and frees up one hand

I replaced the hose on my 20v dewalt grease gun and I put this on it and it is very convenient. I’m sure I will come across a fitting it might not be able to get to at some point but for all normal fittings this is awesome. It doesn’t take both hands to grease anymore

Almost mandatory

This is what all good grease guns should come with. Works flawlessly a it should. No wasted grease because the coupler comes off. Even stalling the grease gun on a blocked fitting still allows for easy removal.Top of the line product.

Too big

Diameter was too big for my application, returned it for Thinkwork brand which is a smaller diameter and works the same.

Great product

Gone are the days of grease squirting out the bottom of the fitting and not going into the zerk fitting. This thing holds tight and forces the grease into the fitting without having to push on it to keep it engaged! Love this thing!

Great connector

If you use a grease gun I wouldRecommend this. Locks on andYou don't have to worry aboutIt coming off while using

Recommend this with the release valve

I got this for my m12 grease gun. I use this almost every day to grease tractors and equipment. It works awsome I also got the release valve to help get it off if there is a stuck fitting and just release the pressure. I highly recommend this.
