Common hydraulic seal materials include polyurethane, nitrile rubber (NBR), fluorocarbon (FKM/Viton), polytetrafluoroethylene (PTFE), and thermoplastic elastomers. Material selection depends on operating temperature, pressure, fluid compatibility, speed, and environmental exposure. Polyurethane offers excellent wear resistance and extrusion protection for high-pressure applications. P... https://globalsealstech.com/hydraulic-seals/
