Review on 🔧 AZUNO Grease Gun Coupler 2nd Gen - 12,000 PSI, Quick Lock & Release, 1/8'' NPT (2 Pack) by Eric Chapman

I was very happy to receive this product and try it, the reviews seem very positive. I never leave a review unless I have fully used the product. I will say the product looks and feels like good quality with the ability to replace parts that might break. I didn't expect it to break so quickly considering I only used it to grease my dump truck and half my tractor before one of the jaws snapped. To be fair, when the jaw broke I squeezed the gun hard to squeeze out the bad Zirk lube. But according to the description, it is rated for 10,000 psi pressure. Of course I didn't have a sensor, but I expected that it wouldn't break so easily. I found it very picky about putting it on Zirk. You have to constantly fiddle with it or squeeze it once before it stops without popping out, which doesn't really save you as much time as a regular tip. I'll see if I can get a replacement but I had higher expectations for this product.
