I know it's hard to admire a valve stem cap, but if it were ever possible (and if you suffer from quarantine blues like me) this might do it for you. I was missing a valve cover on 3 different cars and I wanted to find replacements to close the valves. I've had issues with two valves in the recent past so I think keeping dirt and debris off of them isn't a bad idea. These cases are well made and have a comfortable feel and weight. I mounted them on a couple of tires that didn't have caps over lunch and they all bolted on easily and securely. The threads are well made so they fit perfectly and are snug. In fact, they look so good that I will be replacing all four on each machine and throwing away those old, flimsy, low quality plastic covers. I'm so excited to be able to get off work this morning just to get it done and then relax and marvel at my DIY triumph. Definitely a good buy and keeper.
