We know what you're thinking and no, you can't just use the cap that came off your lawn mower as a valve cap for your aircraft. There's no need to start looking around for a lesser replacement anyway, not when we have such a handsome looking Dill Air Controls 637 yellow brass aircraft valve cap that's tough and designed especially for that purpose. It's proudly made here in the U.S. and really cheap too, so there's no excuse not to pick them up here. This brass valve cap is designed for wrench tightening and it has a special sealing washer for 0-5000 psi and a temperature range of -65 degrees to 160 degrees Fahrenheit. It conforms to military standards MS20813-1. The Tire and Rim Association designation is TRVC5. See our approvals and specifications list for more information.
