Built for the most chemically aggressive and high-temperature hydraulic environments, this Fluorocarbon (FKM/Viton®) O-ring delivers superior sealing integrity where standard elastomers fall short. At 75A Shore durometer, it provides firm, stable compression resistance — ideal for high-pressure dynamic and static sealing applications across industrial, aerospace, and mobile hydraulic systems.
