100-Piece Double Sealing Inflate Through Valve Cap Bulk Pack

Add a second level of protection on high pressure semi, large commercial truck, tractor / trailer, RV, and agricultural vehicle tires with STEELMAN 99069 Double Sealing Inflate Through Valve Caps. These all metal valve stem caps are far more durable than standard plastic caps and feature durable factory fit EPDM rubber seals that provide a second, air-tight seal on valve stems. This gives tires a second level of protection that prevents the build-up of dirt, water, and greasy road grime that can lead to corrosion and damage to valve cores that results in leaks and premature failure. The fill through design allows tires to be checked, inflated, and deflated without having to remove the cap, making servicing tires much faster. Outside is threaded for easy attachment of air hoses for quick inflation or for the use of a second cap. Bulk pack contains 100 individual double sealing valve caps.
