Expanded PTFE/ ePTFE Full Face Gaskets

Expanded PTFE (ePTFE) is a modified form of PTFE that has been expanded to create a microporous, flexible structure. This results in improved compressibility, conformability, and sealing performance, especially on irregular or damaged flanges. At Industrial Experts, we supply Expanded PTFE Full Face Gaskets cut to size for all Australian and international standards, making them the ideal choice for industries where chemical resistance, hygiene, and reliable sealing are critical.

Why Choose Expanded PTFE Full Face Gaskets?

• Universal chemical resistance – suitable for nearly all chemicals, acids, and solvents
• Highly compressible & conformable – seals irregular flange surfaces better than virgin PTFE
• FDA compliant – safe for food, beverage, and pharmaceutical applications
• Temperature range – from –200 °C to +260 °C continuous service
• Non-stick, non-aging material – easy to remove and long-lasting
• Covers full flange face including bolt holes for maximum sealing security

FAQ – Expanded PTFE Full Face Gaskets

Q1: How does ePTFE differ from virgin PTFE?
Expanded PTFE is softer, more compressible, and seals better on irregular surfaces than virgin PTFE.

Q2: Is it suitable for food and pharma use?
Yes – ePTFE is FDA compliant and widely used in hygienic applications.

Q3: What’s the temperature range?
From –180 °C to +260 °C continuous service.

Q4: Can I order non-standard gaskets?
Yes – we manufacture custom profiles with no minimum order.

Q5: Does ePTFE cold flow like virgin PTFE?
It resists creep better than virgin PTFE thanks to its expanded microstructure.
