It is important to determine the correct style and material for your application. Hi-Tech Seals standard wiper material is urethane; however, KasPex™ PEEK, nitrile (NBR), hydrogenated nitrile (HNBR), fluorocarbon/Viton™ (FKM), and Hytrel® materials are available upon request. Things that should be considered when selecting the material of your wiper include:

Wipers are primarily designed to stop contaminants from entering a cylinder on the rod, however, they can also act as a secondary rod seal.
