Exceptional Chemical Resistance

PTFE O-rings are virtually unaffected by acids, alkalis, oils, solvents, and most industrial chemicals, making them ideal for use in aggressive environments where other materials would degrade.

Wide Operating Temperature Range

These O-rings maintain their sealing properties from extremely low to very high temperatures, typically from -200°C up to +250°C (and in some cases even higher), ensuring reliable performance in both cryogenic and high-heat automotive applications.

Low Friction and Non-Stick Properties

PTFE’s naturally low coefficient of friction minimizes wear and prevents sticking, which is especially beneficial in dynamic sealing applications such as pumps, valves, and rotating machinery.

Long Service Life and Durability

Resistant to oxidation, UV radiation, and weathering, PTFE O-rings have a long operational lifespan and retain their properties even after prolonged exposure to harsh conditions.

No Swelling or Absorption

PTFE is hydrophobic and does not absorb water or swell, ensuring dimensional stability and consistent sealing performance over time.

Excellent Electrical Insulation

PTFE O-rings provide outstanding electrical and thermal insulation, supporting their use in electronic and high-voltage automotive components.

FDA Compliance and Non-Toxicity

Virgin PTFE is FDA compliant, making these O-rings suitable for food, pharmaceutical, and medical applications in addition to automotive uses.

Customizable and Easy to Install

PTFE O-rings can be fabricated to precise dimensions, allowing for custom solutions tailored to specific sealing requirements in Conic Auto’s diverse range of applications

PTFE (Polytetrafluoroethylene) O-rings are widely regarded as one of the best sealing solutions for high-temperature environments. Here’s why they excel in these demanding conditions:

1. Exceptional Thermal Stability

PTFE O-rings maintain their mechanical integrity and sealing properties across a broad temperature range, typically from -200°C to +250°C (and in some cases, even higher). This makes them suitable for both cryogenic and extreme heat applications without risk of melting, softening, or becoming brittle.

2. Non-Degrading Material

Unlike many elastomers, PTFE does not degrade, harden, or lose elasticity when exposed to continuous high temperatures. This stability ensures a long service life and consistent performance, even after prolonged exposure to heat.

3. Chemical Inertness at High Temperatures

PTFE’s chemical resistance does not diminish at elevated temperatures. It remains inert to most chemicals, oils, fuels, and solvents, preventing swelling, cracking, or breakdown that can occur with other materials under thermal stress.

4. Low Friction and Non-Stick Surface

PTFE’s low coefficient of friction reduces wear and prevents sticking or bonding to mating surfaces, which can be a problem for other materials at high temperatures. This property helps maintain a reliable seal and reduces maintenance needs.

5. No Outgassing or Contamination

PTFE does not release volatile compounds or degrade into harmful byproducts at high temperatures, making it suitable for sensitive environments such as automotive, aerospace, and food processing.

6. Dimensional Stability

PTFE O-rings maintain their shape and size even when exposed to thermal cycling (repeated heating and cooling), ensuring a consistent and reliable seal over time.
