Parker's P Wiper is a low speed wiper designed to exclude dust and contamination in reciprocating applications. Its materials of construction – a dense outer case and soft, flexible lip – are concentrically molded as a single unit. 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. It is also available in homogenous elastomer, heel and lip, for greater pliability if needed.

Product features include:
• Scraper lip extends outside the bore face
• Designed to exclude dust and contamination
• Used in low speed reciprocating applications
