Best Oil Seal Materials for High-Temperature Applications: FKM, ACM, PTFE, and Silicone

High-temperature oil seal selection depends on more than a material’s stated temperature range. This guide compares FKM, ACM, PTFE, and silicone for rotary sealing applications, explaining their strengths, limitations, fluid compatibility, shaft-speed considerations, and how to choose the right seal material for engines, transmissions, gearboxes, pumps, and industrial equipment.
