Overview
This 4.5-inch spiral wound flange gasket is engineered for high-pressure, high-temperature sealing applications in demanding industrial environments. Constructed with corrosion-resistant 316L stainless steel windings and filler, it is designed to create a reliable, leak-tight seal between flanges. The gasket meets a nominal pressure rating of PN63 (approximately 915 PSI) and conforms to relevant industry specifications for dimensions and performance. Its robust construction ensures long-term service life in systems handling steam, hydrocarbons, chemicals, and other aggressive media.
