Is the IBC Flat PTFE Gasket for PN Flange suitable for use with aggressive chemicals at temperatures down to -200°C and pressures up to 300 bar?

Yes. The IBC Flat PTFE Gasket for PN Flange Format is suitable for use with aggressive chemicals at temperatures down to −200°C and pressures up to 300 bar. Manufactured from high‑quality PTFE and compliant with PN‑EN 1514‑1, it offers excellent resistance to aggressive media and extreme conditions, with an operating range of −200°C to +220°C and a working pressure up to 300 bar. Correct selection must consider the specific medium and exact operating temperature, so consultation with TUBES INTERNATIONAL® is recommended to ensure optimal performance and proper flange OD matching.

Can the IBC Flat PTFE Gasket for PN Flange be used across different flange classes (PN10/PN16/PN25/PN40) while ensuring correct outer diameter and sealing performance?

Yes — the IBC Flat PTFE Gasket for PN Flange can be used across different flange classes (PN10/PN16/PN25/PN40) provided the correct outer diameter is selected and installation/operating conditions are respected. Manufactured to PN‑EN 1514‑1 from high‑quality PTFE, it offers excellent chemical resistance and a broad temperature range (–200 °C to +220 °C) with a working pressure capability up to 300 bar, making it suitable for demanding applications. Key points: - Outer diameter must match the flange class requirements; correct OD selection is essential for proper fit and sealing. - Mechanically, a gasket specified for a higher PN class (e.g., DN10 PN40) is compatible with lower classes (PN25, PN16, PN10) if the OD and bore align. - Final gasket choice should consider the process medium and operating temperature to ensure material compatibility and performance. - Consultation with TUBES INTERNATIONAL® is recommended to confirm the optimal gasket size and specification for your flange class and service conditions.
