LH‑Type wiper seal is a high‑performance hydraulic dust seal specially designed for piston rod protection in reciprocating hydraulic cylinders. As a critical external sealing component, its main function is to scrape off dust, mud, sand, metal chips and other external contaminants from the moving piston‑rod surface before they enter the hydraulic system. Effectively preventing foreign particles from invading the internal hydraulic circuit avoids premature wear of rod seals, guide rings and cylinder inner components.
Manufactured from durable polyurethane material, the LH‑type wiper adopts optimized lip geometry. The outer scraping lip firmly fits the rod surface to remove debris, while its secondary structure provides good adaptability for slight rod eccentricity. It delivers stable scraping performance under harsh working environments such as construction machinery, agricultural equipment and outdoor hydraulic facilities.
LH wiper seal fits standard installation grooves for quick and convenient assembly. It resists low‑temperature aging and abrasion, maintains reliable wiper effect during long‑term repeated reciprocating movements. It works cooperatively with rod seals to extend the whole service life of hydraulic cylinder kits. For heavy‑duty outdoor hydraulic applications, LH‑type wiper seal is a cost‑effective dust‑proof solution to reduce equipment failure and maintenance frequency.
