Actually you shouldn't have caps on your valve stems at all.
Rule #60: Ditch the washer-nut and valve-stem cap.
You are not, under any circumstances, to employ the use of the washer-nut and valve-stem cap that come with your inner-tubes or tubulars. They are only supplied to meet shipping regulations. They are useless when it comes to tubes and tires.
