Key Features of PTFE Exhaust Manifold Gaskets from Conic Auto

Exceptional Chemical Resistance

PTFE (polytetrafluoroethylene) gaskets are highly resistant to a wide range of chemicals and corrosive exhaust gases, ensuring a long service life even in aggressive engine environments.

Outstanding Thermal Stability

These gaskets maintain their integrity and sealing performance across a broad temperature range, typically from -100°C up to 240°C (and even up to 260°C in some grades), making them ideal for the extreme heat of exhaust manifolds.

Low Friction and Wear Resistance

PTFE’s naturally low coefficient of friction minimizes wear, reduces the risk of sticking or binding, and ensures that the gasket remains effective over time, even under constant thermal cycling and vibration.

Non-Stick, Non-Contaminating Surface

The non-adhesive properties of PTFE prevent the buildup of residues and make the gaskets easy to clean and maintain. This also ensures that the gasket does not contaminate the exhaust system or engine components.

Compressibility and Conformability

PTFE gaskets are highly conformable and compressible, allowing them to adapt to uneven or damaged flange surfaces and provide a secure, leak-proof seal.

Odorless and Non-Toxic

PTFE is non-toxic, non-wetting, and odorless, making it suitable for a variety of automotive and industrial applications where cleanliness and safety are important.

Excellent Electrical Insulation

In addition to thermal and chemical resistance, PTFE provides excellent electrical insulation properties, which can be beneficial in applications where electrical isolation is required.

Maintenance-Free Operation

Thanks to their durability, chemical inertness, and non-stick properties, PTFE exhaust manifold gaskets require minimal maintenance and offer a long operational life

PTFE exhaust manifold gaskets from Conic Auto are valued across a wide range of industries due to their exceptional chemical resistance, thermal stability, and durability. The industries that benefit most include:

Automotive Industry

PTFE gaskets are widely used in automotive engines and exhaust systems because they can withstand high temperatures and corrosive exhaust gases, ensuring reliable sealing and long service life for both passenger and commercial vehicles.

Chemical Processing

Due to their resistance to aggressive chemicals and high temperatures, PTFE gaskets are essential in chemical plants for sealing pipes, valves, and machinery where contamination and leakage must be avoided.

Oil & Gas and Energy Sector

PTFE gaskets are used in oil and gas pipelines, power plants, and other energy systems, providing leak-proof performance in environments with high pressure, temperature, and exposure to harsh chemicals.

Food and Pharmaceutical Industries

PTFE’s non-stick, non-contaminating, and chemically inert properties make these gaskets ideal for food processing and pharmaceutical manufacturing, where maintaining product purity and preventing contamination are critical.

Aerospace and Industrial Equipment

The aerospace sector and various industrial machinery manufacturers utilize PTFE exhaust manifold gaskets for their ability to maintain tight seals under extreme conditions, ensuring equipment reliability and safety
