FKM PTFE O-Ring | O Ring Seal | High-Temp Chemical-Resistant Seal
Product Description
This O-Ring, sized 6x1.4mm, is a high-performance sealing component combining FKM70 (Viton) rubber with a white PTFE (Teflon) coating. The FKM70 core delivers exceptional resistance to temperatures from -20°C to 200°C and aggressive chemicals, while the PTFE coating adds a low-friction, anti-adhesive layer that prevents material buildup and ensures hygienic performance. Its white, one-piece circular design fits standard seal grooves in food processing equipment, pharmaceutical machinery, and chemical pipelines, creating a durable barrier against fluid leakage. This dual-layer construction makes it ideal for critical sealing applications where hygiene, chemical stability, and low friction are essential.

Advantages
- Extreme Temperature & Chemical Resistance: FKM70 withstands -20°C to 200°C and resists acids, alkalis, and solvents, while PTFE enhances resistance to aggressive media.
- Low-Friction & Anti-Adhesion: The PTFE coating reduces surface friction, minimizing wear and preventing product buildup, which is critical for food and pharmaceutical applications.
- Hygienic & Non-Toxic: White PTFE coating meets FDA and EU food contact standards, ensuring safety in hygienic environments.
- Enhanced Durability: Dual-layer construction combines FKM’s elasticity with PTFE’s abrasion resistance, extending service life by 30-50% compared to uncoated FKM O-rings.
- Universal Compatibility: Standard circular cross-section fits most equipment seal grooves, enabling direct, tool-free installation.
Applications:
- Seals food processing machinery and pharmaceutical equipment, where hygienic performance and anti-adhesion are critical.
- Provides high-temperature sealing in chemical pipelines and reactors, preventing leakage of corrosive media.
- Reduces friction in hydraulic system cylinders and valves, maintaining pressure stability and extending component lifespan.
- Ensures leak-proof performance in new energy vehicle fuel systems, resisting hydrogen and coolant corrosion.
- Protects industrial pumps and compressors from abrasive wear, supporting continuous operation in harsh environments.
