H₂S FFKM O-RING
H₂S-Resistant Sealing for Harsh Oil & Gas Applications
Description：
Exceptional H₂S and Sour Gas Resistance
Specially formulated to resist degradation from hydrogen sulfide (H₂S), sour hydrocarbons, and other reactive gases commonly found in oilfield and petrochemical processes.
Thermal Stability
Performs reliably across a wide temperature range from -10°C to 230°C, maintaining elasticity and sealing force under thermal cycling.
Broad Chemical Compatibility
Withstands exposure to acids, bases, hydrocarbons, amines, solvents, and steam—making it suitable for a wide range of chemical and high-pressure applications.
Long-Term Compression Set Resistance
Delivers consistent sealing over time, even in dynamic, high-pressure environments thanks to a robust peroxide curing system.
