PTFE DIN 125 Washers ISO 7089 Flat Washer Teflon Plain Ring Gasket

Description

PTFE DIN 125 washers (Polytetrafluoroethylene) offer exceptional chemical resistance, low friction, thermal stability, and electrical insulation, making them ideal for industrial, chemical, food processing, and medical applications. These washers are widely used in sealing, insulation, and anti-corrosion environments where metal or other plastics may fail. Ever Hardware provides custom made fasteners and customizable packaging.

Key Advantages

1. Exceptional Chemical Resistance
• Highly resistant to acids, bases, solvents, and corrosive chemicals, making it superior to nylon, rubber, and metal washers.
• Ideal for chemical processing, pharmaceutical, and laboratory equipment where exposure to aggressive substances is common.

2. Extreme Temperature Resistance
• Can withstand temperatures from -200°C to +260°C (-328°F to 500°F) without degrading.
• Perfect for high-temperature sealing applications in automotive, aerospace, and industrial machinery.

3. Low Friction and Anti-Stick Properties
• Ultra-low coefficient of friction provides smooth movement in rotating and sliding applications, reducing wear.
• Non-stick surface prevents material buildup, making it ideal for food processing and pharmaceutical applications.

4. Excellent Electrical Insulation
• Non-conductive, making it suitable for electrical and electronic applications where insulation is required.
• Maintains stability under high-voltage and high-frequency environments.

5. Water and Moisture Resistance
• Non-absorbent, ensuring zero water absorption and making it highly resistant to humidity and moisture damage.
• Ideal for marine, plumbing, and outdoor applications.

6. FDA & Medical-Grade Compatibility
• Non-toxic and food-safe, compliant with FDA and medical industry standards.
• Used in food production, medical devices, and sterilized environments.

7. Non-Magnetic and Non-Reactive
• Non-magnetic and chemically inert, ensuring it does not interfere with sensitive electronic or laboratory instruments.
• Safe for biomedical and high-precision engineering applications.

Common Applications
• Chemical & Industrial Processing – Corrosion-resistant sealing.
• Electronics & Electrical – High-voltage insulation.
• Aerospace & Automotive – High-temperature, low-friction components.
• Medical & Food Processing – FDA-compliant non-stick sealing.
• Marine & Plumbing – Water-resistant and non-corrosive washers.

Conclusion

PTFE DIN 125 Flat Washers (ISO 7089) provide superior chemical resistance, extreme temperature stability, electrical insulation, and low friction, making them a premium choice for demanding industrial, medical, electronic, and chemical applications.
