Skull Schrader Valve Caps. Spice up your rim, with the skeleton within!Fits any standard Schrader Valve. There are two styles of files for this model. One is for valve stems pointing straight upward (such as on bicycle tires) with the female threaded hole at the bottom of the skull underneath the chin. The second is for valve stems that point outwards from the rim (such as on car tires) with the female threaded hole in the back of the head of the skull.

Great for bicycles, cars, motorcycles, and anything else that has a Schrader Valve!
