Overview
This DN400 stainless steel flange gasket is engineered for high-pressure, high-integrity sealing in demanding industrial piping systems. Designed to withstand operating pressures up to 63 PSI, it provides a reliable, leak-tight barrier in critical applications where system failure is not an option. The gasket features a robust D-shaped construction with integrated inner and outer metal rings, ensuring precise alignment on the flange face and preventing gasket blow-out or buckling under high bolt loads. Its corrosion-resistant materials make it suitable for a wide range of aggressive media and high-temperature environments.
