LH type wiper dust seal is installed on the rod side of hydraulic cylinders to scrape off dust, mud, sand and other debris from the moving piston rod. It prevents external contaminants entering the hydraulic system and protects internal sealing components from abrasion damage.
Made of high-quality elastomer material, the LH dust seal features flexible lip design, good wear resistance and weather resistance. It maintains stable wiping performance under frequent reciprocating motion, without scratching the rod surface. Widely used in construction machinery, injection molding machines and general industrial hydraulic equipment. Precision dimensional control ensures convenient installation and long working life.
