ePTFE Gaskets: High-Integrity Sealing at Lower Bolt Loads

Why ePTFE Gaskets Are a Smart Choice for Demanding Applications

Expanded PTFE (ePTFE) gaskets are engineered to deliver reliable sealing performance across a wide range of industrial environments. Known for their flexibility, chemical resistance and adaptability to flange irregularities, they provide effective sealing even at lower bolt loads.

This ability to seal under reduced compression makes them particularly valuable in applications where flange stress, equipment integrity and long-term reliability are critical.

Performance Benefits

Effective Sealing at Lower Bolt Loads
ePTFE’s compressibility allows it to conform to flange surfaces, reducing the need for excessive bolt torque. This helps minimise stress on flanges and connected equipment.

Excellent Chemical Resistance
Suitable for a broad spectrum of media, ePTFE performs well in chemically aggressive environments.

Dimensional Stability
Resistant to creep and cold flow compared to conventional PTFE, supporting consistent long-term sealing.

Sustainability Advantages

Durable sealing contributes directly to operational sustainability:

• Longer service life reduces replacement frequency

• Reduced leakage lowers energy and product loss

• Lower bolt load reduces mechanical strain and maintenance risk

• Fewer failures minimise downtime and material waste

By improving reliability and efficiency, ePTFE gaskets support more sustainable and cost-effective operations over time.
