Teflon gasket flange seal

Teflon gasket flange seal

Teflon flange gaskets offer excellent chemical resistance, wide temperature tolerance, and low friction sealing, ensuring leak-free, long service life performance in corrosive industrial applications.

 Main Structural Features

• Temperature: -200 °C to +260 °C for both low- and high-temperature chemical systems.
• Pressure: Up to 10–25 bar, depending on gasket type and flange standard.
• Chemical resistance: PTFE is inert to 99% of industrial chemicals, including acids and alkalis.
• Low friction: Coefficient ≈ 0.04, reducing bolt load and improving sealing reliability.
• Standards & sizes: Compatible with ANSI / DIN / JIS, sizes from DN15–DN600.

 FAQ for Teflon gasket flange seal:

Q: Do Teflon flange gasket seals require high bolt torque?
A: No. Due to PTFE’s low friction and compressibility, effective sealing is achieved with lower bolt torque compared to metal gaskets, reducing flange stress.

Q: Are Teflon gasket flange seals suitable for high-purity applications?
A: Yes. PTFE gaskets are non-contaminating and non-reactive, making them ideal for high-purity chemical and pharmaceutical processes.
