Want the best permanent valve stem on the market? Our Ultimate Valve System is it!


It is a full 1/2" shorter than our original Permanent Valves, lowering the risk that it will contact hazards on the trail. If it does, the high strength will further protect you against a valve stem break.


These are .453 size, and will fit everything from bicycles to truck tires.
