Rubber composition and design for snap-in tire valve

摘要

A snap-in tire valve for mounting in a valve hole in a wheel rim, having a valve body and a resilient member having an overall shape including a groove and a rib adapted to snap into and be retained in the hole. The resilient member may include a rubber that is the reaction product of ethylene-propylene copolymer elastomer, a peroxide curative, zinc diacrylate or zinc dimethacrylate, and a high-density inert filler, such as barium sulfate. The resilient member may include a first and second rubber members of different compositions from each other and defining two layers under the groove. The thickness of the layer of the first rubber member is preferably greater than the thickness of the layer of the second rubber member.
