OUTSTANDING results.

This product lives up to the hype. I used it for the first time today on a 2021 Chevy 3500 Express Van. I had absolutely no issues greasing all 11 zerk fittings. The one thing you need to watch for is over lubing the joints. I noticed it put out more grease then the stock bit on my basic grease gun. Buy it now.

100% worth every penny

I was ready to give up and could not figure out why the grease wouldn't go into the fitting. I bought two grease guns and neither worked. My last hope was buying this thing and it was kinda pricey but not more than any alternative and it worked perfect right away.. this thing is awesome

Works great where it fits.

This the go-to coupler when I'm greasing the points. it's on the large side, so it does not fit all the points I need to hit, but I always use it to do what it can do and then switch it out with a smaller straight coupler to get the difficult ones.

Must have tool! Speeds up lube process!

Used it today and I was kicking myself for not buying this awesome, locking tool sooner! Stays on the grease fitting until your done. You're able to use both hands to pump your grease gun & focus on the bearing for the new grease squirting out. So much easier!

Woks good

Works good just doesn’t fit in tight spots , but good product!

Worth it!

Gone are all of my grease fitting troubles. It simply does what it’s supposed to do. All of the grease goes into the zerk fitting and nothing leaks out. Well worth the price.

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.
