Detailed Product Description

Highlight:

FKM Teflon O-Ring seal

high-temperature O-Ring seal

chemical-resistant O-Ring 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.
