HERCULES WIPER SEAL

Replacement and service applications are exactly what this seal is built for. Hercules Sealing Products makes it as an equivalent-grade component, so it fits right into standard industrial hydraulic cylinder rod sealing systems the same way an OEM part would. It mounts at the outer edge of the cylinder head and contacts the rod on the return stroke to scrape off dirt, dust, and moisture before any of that mess gets to the inner sealing elements. As long as your cylinder takes a KW-3000, you're in good shape. It also crosses over to part numbers C1DD18, MI-02227768, and MINO-00407X30543 if you're trying to match it against something in your records.

On a hydraulic cylinder, a wiper seal sits at the outer edge of the cylinder head and rides on the rod. When the rod retracts, it scrapes dirt, dust, and moisture off the rod surface so that contamination does not get carried into the inner sealing elements.
