Our FEPM-E O-Rings are engineered from premium FEPM-E fluoroelastomer (similar to Viton™ ETP), designed to withstand aggressive chemical exposure in high-temperature, high-pressure environments. Offering excellent resistance to alkalis, acids, amines, and solvents, this O-ring is a cost-effective alternative to FFKM, without compromising on performance or durability.
Exceptional Chemical Resistance
Formulated to resist harsh chemical environments, including concentrated acids, caustics, amines, and a broad range of solvents—ideal for reactors, valves, and containment systems.
Thermal and Mechanical Stability
Maintains sealing performance under continuous temperatures up to 230°C, offering strong resistance to thermal cycling and mechanical stress.
FFKM-Like Performance, Lower Cost
Delivers near-FFKM chemical resistance and reliability at a significantly lower price point, making it suitable for cost-sensitive, high-risk applications.
Versatile Across Industries
Perfect for chemical processing, petrochemical refining, oil & gas systems, and steam-handling applications, including environments with high chemical saturation.
