Custom FFKM Rubber Seals: Ultimate Solution for Extreme Conditions(2026version）

What Are Custom FFKM Rubber Seals?

Key Features & Benefits

• Extreme Temperature Resistance: Stable from -45°C to 335°C (short-term peaks up to 350°C), suitable for cryogenic and high-heat processes.
• Unrivaled Chemical Inertness: Resists 1800+ corrosive substances (acids, bases, solvents, plasmas, H₂S), ideal for aggressive media.
• Low Compression Set: Maintains elasticity under prolonged pressure, ensuring consistent sealing in dynamic/static applications.
• High Purity & Low Outgassing: Meets semiconductor-grade cleanliness (Class 10), perfect for vacuum systems and sterile processing.
• Long Service Life: Reduces replacement frequency and downtime, lowering total operational costs.

Primary Applications

• Semiconductor & Electronics: Plasma chamber seals, vacuum system components, wafer processing equipment.
• Petrochemical & Oil/Gas: Wellhead seals, valve gaskets, pipeline components (resists H₂S and high pressure).
• Aerospace & Defense: Engine hot-section seals, hydraulic/fuel system components, cryogenic fuel storage.
• Pharmaceutical & Food: FDA-compliant seals for reactors, sterile filters, and high-temperature sterilization equipment.
• Chemical Processing: Reactor gaskets, pump seals, and flange components handling aggressive solvents.
