The ASC-HT valve with complete new sealing concept is an all purpose metal valve for highly stressed wheels of fast moving cars; sprinters and any vehicles with high tire pressure and high tire temperature.In traditional metal valves; the pre-load of the fastening nut is channeled through the rubber seal. This results in inevitable aging and decreasing sealing efficiency; even to the point of loosening the valve. With the ASC leak-proof concept; the pre-load is set by the interface between the edge of the valve's metal cup and the tire rim. Therefore the pre-load is led directly into the metal of the rim. A plastic washer prevents damage to the rim while torquing the nut.The seal can perform its function independent of external forces. Pressure range of up to 200 PSI
