PDU Wiper Seal – Compact Double-Lip Hydraulic Excluder with Integrated Sealing Function.
PDU compact double-lip wiper seal for hydraulic cylinders. Scrapes contaminants, retains lube, provides backup sealing. PU, –35°C~110°C, ≤10 MPa.
PDU Wiper Seal – A compact double-lip hydraulic wiper seal engineered for contamination control and light fluid sealing in space-constrained applications. This dual-purpose excluder features a primary scraper lip that efficiently removes dirt, dust, and moisture from the rod surface during retraction. The secondary sealing lip retains internal lubricant film and provides supplemental fluid sealing to prevent micro-leakage, offering dual-layer protection in a single compact profile. The interlocking profile ensures secure groove retention under vibration and pressure fluctuations, while the optimized lip geometry delivers low friction and minimal rod wear. This compact wiper seal is ideal for hydraulic cylinders, pneumatic actuators, and automation equipment where space is limited. Material: high-performance polyurethane. Temp: –35°C to +110°C. Pressure: up to 10 MPa (when used as secondary seal).
