Review on 🔧 Lumax LX-1404 Silver 90 Degree Grease Coupler: Ultimate Solution for Tough-to-Access Grease Fittings on Vehicles & Farm Equipment. Ideal for Front/AWD Lubrication. by Gary Newman

Sorry I have to agree with the lower rated reviews. I had to unscrew the top as the coupler it attaches to doesn't work in my grease gun. In addition, the rounded and smooth top that tightens and loosens makes it extremely difficult to operate, especially considering the type of use this tool is intended for (lubrication). I had to use a multitool to draw this thing from scratch. Other than that, I managed it pretty well. It ended up lubricating my tractor but causing a few headaches in the process. Another swipe, if too loose the metal jaws will fall out, and by too loose I mean quite a bit.
