LDH Wiper Seal – Heavy-duty double-lip excluder with integrated secondary sealing function. Primary scraper lip efficiently removes dirt, mud, and ice from the rod surface during retraction strokes. Secondary lip provides supplementary fluid sealing, retaining lubrication film and preventing external contamination ingress. Optimized lip geometry ensures low friction and reduced wear on the rod surface. Robust cross-section provides secure groove retention under vibration and shock loads. Excellent resistance to weathering, ozone, and hydraulic fluids. Ideal for construction, agricultural, and industrial hydraulic cylinders exposed to moderate contamination levels. Material: high-grade polyurethane. Temp: –35°C to +110°C. Pressure: up to 10 MPa (when used as secondary seal).
LDH Wiper – Double-lip heavy-duty excluder. Scrapes contaminants, retains lube, provides backup sealing. Low friction, secure retention. PU. –35°C~110°C / ≤10 MPa.
LDH Wiper Seal – Two lips, double duty. Cleans, seals, and protects — all in one.
LDH Wiper Seal – Double-lip excluder with primary contamination scraping and secondary fluid sealing functions. Low-friction design minimizes rod wear. Robust profile resists extrusion and vibration. For medium-duty hydraulic applications. PU. –35°C to 110°C, up to 10 MPa.
