The YT® FEPM AFLAS O-ring is a fluororubber with a peroxide curing system, featuring a unique monomer structure that resists aggressive oils and provides excellent resistance, including to alkalis and steam.

YT® FEPM AFLAS O-rings exhibit outstanding durability against strong chemicals such as acids, alkalis, and amines. This is an exceptional characteristic not found in general vinylidene fluoride rubbers like FKM. Moreover, they maintain this superiority even under high concentrations or temperatures of these chemicals, particularly demonstrating excellent durability against amine-based chemicals.

The superior chemical resistance of the YT® FEPM AFLAS series includes:
• ATF transmission fluid
• Low-temperature steam
• Amine-based fluids
• Optimal mechanical properties
• Optimal cost-performance ratio
• Etching solutions
• Petroleum drilling production
