Designed for high pressure truck tire service. Inflate, deflate or gauge directly through the DS-1 saving time during inflation and pressure checks. Automatic inflation systems lock right onto the DS-1. Seals like a high pressure cap, yet offers the convenience of an inflate-thru extension. The DS-1 performs like a check valve - the seal becomes tighter in the event of a core failure. Heat resistant grommets provide additional protection for extended high temperature running. Features tough all metal housing, precision fit brass components and durable self-sealing O-Ring.


  • A time, money and labor saving alternative to common valve caps.
  • Reduce pressure check time by 65%
