Wiper Seals

KOK wiper seals are designed to prevent external contamination from entering hydraulic systems through the reciprocating rod. Proper contamination exclusion is essential to extending cylinder life and preventing premature seal wear.

Wiper selection depends on rod surface finish, operating environment, and expected exposure to debris, mud, or abrasive particles.

• Single-lip and double-lip profiles
• Metal-cased and elastomeric designs
• Standard and heavy-duty contamination environments
