Parker’s Sliptite Clipper® Oil Seals are general purpose, single lip rotary shaft seals which have a layer of PTFE bonded to the elastomer sealing lip. The bonded PTFE layer reduces the frictional heat from lip contact force, thereby reducing excessive wear on the shaft and seal. As a result, seal profiles may be used in dry running applications and at higher speeds. In addition, PTFE enhances fluid compatibility with its broader range of chemical acceptance.

General purpose, PTFE-lined Clipper oil seals are available in spring-loaded and springless designs and provide excellent retention of grease and oil. The seal’s non-metallic, composite rubber/aramid fiber OD, or “heel,” forms a leak-free, press fit in the housing, conforming to minor surface irregularities. In the spring-loaded LUP, LPD, RUP, and RPD designs a stainless steel garter spring provides constant, uniform load of the lip on the shaft for the life of the seal. The spring keeps the elastomer lip in contact with the shaft during higher shaft speeds and also helps offset normally occurring compression set and wear of the lip material. The SS style is springless.
