Overview
This high-performance metal wound flange gasket is engineered for critical sealing in high-pressure and high-temperature piping systems. Designed to a DN300 nominal bore (approximately 12 inches), it is constructed for PN40 pressure class service, suitable for operating pressures up to 580 PSI. The gasket's robust C2220 spiral wound design provides a resilient and reliable seal that compensates for flange face irregularities and system vibration, ensuring long-term leak prevention in demanding industrial environments.
Key Features
