A rotary pneumatic seal may have a ring-shaped inner radial seal with an inner lip extending in an axial direction, an outer lip extending in the same axial direction, a connecting flange connecting the inner lip and the outer lip, a pneumatic sealing lip, and an oil sealing lip. The rotary pneumatic seal may also have a ring-shaped outer radial seal located radially outward from the inner radial seal. The outer radial seal may also have a first wall extending in an outward radial direction, a second wall extending in an opposite inward radial direction, a central flange connecting the first and second walls, and a dust lip.
