Benefits
High Temperature Stability
Capable of continuous operation up to +200 °C, with specialty grades up to +250 °C–300 °C.
Superior Chemical Defense
Withstands fuels, oils, acids, solvents, and ozone. Ideal for hydraulic seals, fuel systems, and chemical pipelines.
Long Service Life
Durable against aging, UV exposure, and compression, minimizing maintenance and replacements .
Dynamic Performance
Handles wear and friction in dynamic rotary and sliding seals, including pump shafts and valve stems.
Vacuum & Leakage Protection
Low gas permeation makes FKM a top choice for vacuum equipment including aerospace and semiconductor systems.
Applications
Automotive & Aerospace: Fuel injectors, seals in engines/transmissions, hydraulic systems.
Chemical & Petrochemical: Aggressive fluid pipelines, refinery pumps, valves.
Industrial Machinery: Compressor seals, hydraulic actuators, chemical process pipelines.
Food & Pharma: FDA/USP-compliant options available for direct-product-contact seals.
Choosing the Right FKM O‑Ring
Size & Standards: Select by AS568 or metric standards for correct ID, OD, and cross section.
Temperature Rating: Base selection on application max ambient and fluid temperature.
Material Grade: Choose standard FKM or extended/-40 °C grades based on low-temp requirements.
Durometer Selection: 70A for typical use, 90A for higher pressure resistance, 50A for sealing flexibility.
Media Compatibility: Always verify the molding grade against your fluid media (e.g., avoid ketones).
