LBH Wiper Seal – Double-Lip Heavy-Duty Excluder

LBH Wiper Seal – Heavy-Duty Double-Lip Hydraulic Excluder with Integrated Sealing Function.

LBH heavy-duty double-lip wiper seal for hydraulic cylinders. Scrapes contaminants, retains lube, provides backup sealing. PU, –35°C~110°C, ≤10 MPa.

LBH Wiper Seal – A rugged heavy-duty hydraulic wiper seal engineered for contamination control and light fluid sealing in medium-duty hydraulic applications. This double-lip excluder features a primary scraper lip that efficiently removes dirt, dust, mud, and moisture from the rod surface during retraction. The secondary sealing lip retains internal lubricant film and provides supplementary fluid sealing, preventing micro-leakage and contamination ingress. The reinforced heel design resists pressure-induced deformation and prevents extrusion, ensuring secure groove retention under vibration and shock loads. The optimized lip geometry ensures low friction and reduced rod wear, extending cylinder service life. This dual-purpose wiper seal is ideal for construction equipment, agricultural machinery, 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).
