ABSTRACT:
A fluid seal device for use in sealing an annular space between an internal surface of a cylinder and a member therein having an outer cylindrical surface and being formed at least in part from rubber. An oleamide additive is included in the rubber compound comprising about 1.0%–5.0% by weight of oleamide. The oleamide additive to the rubber of the fluid seal device results in a reduced coefficient of friction and low speed vibration as well as enhanced abrasion resistance.
