Hydraulic ODU piston PU seal
ODU Piston seals are work to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.
ODU Piston seal is a lip-seal which fits tightly in the groove.
|
Advantages:
1. Unusually high abrasion resistance.
2. Insensibility against shock loads and pressure peaks.
3. Low compression set.
