Schrader Double Seal Valve Cap

Schrader Double Seal Valve Cap eliminates the need for valve caps on truck valve stems, effectively reducing tire service time in fleet operations. A rubber washer seals at the valve mouth and a o-ring seals at extension mouth. Extension is ribbed to allow use of clip-on air chucks. Inflate or deflate the tire directly through the valve cap. Nickel plated brass housing is threaded to hold a locking chuck and cap. Sold individually. Ascot Part #468-01046.
