WS-SEALS A1 Dust Piston Rod U Cup PU Wiper Hydraulic seals

Their main features  are as follows: 

- Dirt Prevention: They are primarily designed to keep out dust, dirt, sand, and metal shavings, safeguarding the internal components of the equipment from contamination.

- Scratch Resistance: With a special design, they can prevent scratches on the surface of moving parts like piston rods, thus protecting the guiding components and prolonging the service life of the seals.

- Good Sealing Performance: The outer diameter with interference fit can ensure that the wiper seal is tightly installed in the groove, preventing the intrusion of foreign particles and moisture, and achieving a good static sealing effect.

- High Wear Resistance: PU material endows A1 wiper seals with excellent wear resistance, enabling them to maintain good performance under long-term use and harsh conditions.

- Wide Temperature Resistance: It can adapt to a wide temperature range. Different formulations are available for high-temperature, low-temperature, and standard temperature applications.
