PDU Wiper Seal – Compact dual-lip excluder with integrated light-duty sealing function. Primary scraper lip efficiently removes dust, dirt, and moisture from the rod surface during retraction. Secondary lip retains internal lubricant film and provides supplemental fluid sealing to prevent micro-leakage. Interlocking profile ensures secure groove retention under vibration and pressure fluctuations. Optimized lip geometry delivers low friction and minimal rod wear. Suitable for compact 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).
PDU Wiper – Compact dual-lip excluder: scrapes dirt, retains lube, provides backup sealing. Low friction, secure retention. PU. –35°C~110°C / ≤10 MPa.
PDU Wiper Seal – Two lips, double protection — keeps contamination out, keeps lubrication in.
PDU Wiper Seal – Compact dual-lip excluder for rod protection. Primary lip wipes external contaminants; secondary lip retains lubrication film. Reliable groove retention, minimal compression set. For space-constrained hydraulic cylinders. PU. –35°C to 110°C, up to 10 MPa.
