PS08 Piston Seal PTFE+BR40/NBR

PS08 Piston Seal is a high-performance composite piston sealing element designed to reliably seal the piston chamber and prevent fluid leakage to the atmosphere or between mating chambers.
The seal features a low-friction PTFE slip ring combined with an elastomer O ring, ensuring excellent sealing performance at both low and high operating speeds.
