Is the DIN 11851 Coupling Gasket, Viton compatible with steam and aggressive chemicals at up to +200°C?

Yes. The DIN 11851 Coupling Gasket, Viton is compatible with steam and aggressive chemicals up to +200°C. Made of high‑quality FPM (FKM) fluorinated rubber (Viton), it offers temperature resistance from -20°C to +200°C and excellent chemical resistance, making it suitable for hot media, aggressive chemicals, oils and steam in hygienic pipeline and process systems.

Can the DIN 11851 Coupling Gasket, Viton maintain a hygienic seal during repeated temperature cycles between -20°C and +200°C?

Yes. The DIN 11851 Coupling Gasket, Viton is specifically formulated to maintain a hygienic, leak‑tight seal through repeated thermal cycling between −20°C and +200°C. Made of high‑quality FPM (FKM) fluorinated rubber (Viton), it offers stable elastomeric properties across this full temperature range, resisting hardening at low temperatures and excessive softening or flow at high temperatures. Its chemical and steam resistance, combined with wear and pressure resilience, preserves flange contact integrity and prevents contamination even during intensive operating cycles. For hygienic process lines—food, beverage, pharmaceutical and biotech—this gasket’s material performance and compliance with hygienic standards ensure continued sealing reliability and reduced maintenance across repeated temperature excursions within the specified range.
