Air Tight Solutions' new AS100 valve stem

Reduce maintenance costs with Air Tight Solutions' new AS100 valve stem from Imperial Supplies, Inc. Unlike standard valve stems with rubber grommets that break down in high temperatures, Air Tight Solutions uses a combination of Viton o-rings and a machined brass adaptor. Viton o-rings and brass adaptors are not affected by high temperatures, thus maintaining a tight seal and accurate tire pressure.
