Material selection for hydraulic seals depends on fluid compatibility, temperature range, pressure level, speed requirements, and environmental conditions. Common materials include nitrile rubber (NBR), polyurethane (PU), fluorocarbon (FKM), ethylene propylene (EPDM), and polytetrafluoroethylene (PTFE), each offering distinct performance characteristics for specific applications. https://globalsealstech.com/hydraulic-seals/
