Always use a true double seal cap


Myers-Inflate-Thru-Valve-Cap.jpgWith a double seal valve cap, guaging, inflation and deflation can be done without having to remove the cap.  

Besides those time saving benefits, a true double seal valve cap incorporates two built-in heat resistant seals which prevents air pressure loss, even if the valve core is damaged or dirty.

The seal is located away from the opening, reducing contamination and risk of leakage.
