Inflate, deflate or gauge directly through the DS-1 dual seal valve cap to save time during inflation and pressure checks. Automatic inflation systems lock right onto the DS-1 valve cap. Seals like a high pressure cap, yet offers the convenience of an inflate through extension.
The DS-1 performs like a check valve - seal becomes tighter in the event of core failure. Heat resistant grommets provide additional protection for extended high temperature running. Features tough metal housing, precision fit brass components and durable self-sealing O-Ring.
A time, money and labor saving alternative to common valve caps.
I just got new tires again. Went with new valve stems and double seal valve caps. Last ones were fine, but 10 more years is a lot to ask. These make it so much quicker & easier to check pressures or add air. Well worth it. I bought the 50 pack so I can put them on my other Trailers and vehicles.
