The D-05375 Wiper AU is a precision-engineered urethane (AU) wiper seal designed to exclude contaminants — including dirt, dust, and moisture — from hydraulic cylinder rod systems. Its aggressive wiping lip geometry ensures reliable scraping action across a wide range of operating conditions, protecting internal seals and extending cylinder service life.
