I just found the time to mount it on the rear inner wheel of my RV. I screwed it on and the hose snapped off the mating nipple. Factory never crimped! It slipped off the stud and I lost a lot of air before I could remove it from the tire valve stem. Not happy at all. Bad quality control. Suggest anyone who buys this item to find the pinch on the end of the valve stem to make sure it's the right one. I'm hoping I can find a local company on 8/22/20 that can crimp it right for me
