FKM Teflon O-Ring | O Ring Seal | High-Temp Chemical Seal
NBR70 O-Ring | O Ring Seal | Oil-Resistant Industrial Seal
Product Description
This FKM Teflon O-Ring, sized 16.00x2.50mm, is a high-performance sealing component built for extreme industrial conditions. Its core is made of FKM 60 (Viton) rubber, which inherently resists temperatures from -20°C to 200°C, while a durable black Teflon (PTFE) coating adds a low-friction, anti-adhesive layer. This dual-layer design creates a robust barrier against fluid and gas leakage, even in environments with aggressive chemicals, high heat, and mechanical wear. The black, one-piece circular structure fits standard seal grooves in chemical reactors, automotive engines, and hydraulic valves, ensuring reliable, long-lasting sealing performance. Combining FKM’s chemical stability with Teflon’s lubricity, it is an ideal choice for critical applications where reliability and longevity are essential.

Advantages
- Extreme Temperature Resistance: The FKM 60 core maintains sealing integrity from -20°C to 200°C, with short-term tolerance up to 220°C, making it suitable for high-heat industrial processes and automotive exhaust systems.
- Superior Chemical Compatibility: FKM rubber resists most acids, alkalis, solvents, and petroleum-based fluids, while the Teflon coating further enhances resistance to aggressive chemicals like strong acids and oxidizing agents.
- Low-Friction & Anti-Adhesion: The black Teflon coating reduces surface friction, minimizing wear during dynamic operation and preventing material buildup, which is critical for food, pharmaceutical, and chemical processing equipment.
- Enhanced Durability: The dual-layer construction combines FKM’s elasticity with Teflon’s abrasion resistance, reducing compression set and extending service life by 30-50% compared to uncoated FKM O-rings.
- Universal Installation: The standard circular cross-section and precise dimensions fit most industrial equipment seal grooves, enabling direct, tool-free replacement without additional machining or customization.
- Contamination Protection: The Teflon coating creates a non-stick surface that repels dust, dirt, and debris, ensuring consistent sealing performance even in dirty operating environments.
Applications:
- Seals chemical processing reactors, pipelines, and valves to prevent leakage of corrosive media, ensuring workplace safety and process efficiency.
- Acts as a high-temperature oil seal in automotive engines, turbochargers, and exhaust systems, protecting lubrication systems from heat and chemical degradation.
- Provides dynamic sealing for hydraulic and pneumatic cylinders, reducing friction and wear to maintain pressure stability and component lifespan.
- Ensures hygienic sealing in food and pharmaceutical machinery, where the Teflon coating’s non-adhesive properties prevent product buildup and simplify cleaning.
- Seals fuel systems in new energy vehicles, resisting the corrosive effects of hydrogen and battery coolants to support reliable operation of electric and hydrogen-powered vehicles.
- Protects industrial pumps and compressors from abrasive wear, extending equipment uptime and reducing maintenance costs in heavy-duty manufacturing environments.
