Saw these mentioned on another group. Supposed to be stronger and available in a shorter length than other valve stems. Would seem like a good option for external TPMS sensors. A big feature which might make them a great road side emergency item is that they can be installed while the tire is on the rim. Would certainly beat a tire change if you experienced a valve stem failure. There is a tool-free option available for emergency use.
