Abstract:
1. A dust cap for use on an automotive wheel having an O-ring installed in a groove formed within the wheel, comprising: a cup-shaped member having a closed end and an open end adapted for engagement with said wheel; a circumferential land adjacent said open end and being formed with a first set of threads located on an external portion of said cup-shaped member, said first set of threads being engagable with a second set of threads formed on said wheel, said land having a smaller diameter than said groove to permit said first set of threads on said dust cap to engage said second set of threads on said wheel without interference from said O-ring mounted in said groove; a shoulder extending radially outwardly from the land to engage said O-ring supported on said wheel within said groove to engage an exterior surface of said cup-shaped member after said dust cap has been partially threaded onto the wheel, said shoulder causing said O-ring to be compressed when said dust cap is fully threaded into said wheel to affect a seal between said dust cap and said wheel and to impose a radial load on said exterior surface of said dust cap to restrict rotation of said dust cap relative to said wheel.
