Product Description: Air Mount™ Dual Tire Inflators Easy to install, no special tools required, the hoses attach to your existing valve stem (no need to remove valve core) allowing proper inflation and pressure checks in seconds. Each kit comes complete with everything you need for the specific wheel application. These heavy duty inflators are constructed of high quality two ply rubber tubing reinforced with a tough nylon braiding. For added protection a stainless braided hose wrap is available to withstand the elements and road hazards. Airless Tire Inflators contain zero internal pressure so they can't leak even if cut or damaged. The interior of hose does not contain air unless the adjustable core actuator within the hose is engaged when checking and inflating tires. For Steel Wheels.
