Overview
This 304 Stainless Steel Spiral Wound Gasket is engineered for demanding, high-pressure sealing in outdoor piping systems. It is specifically designed for use on DN100 (approximately 4-inch nominal pipe size) flanges with a PN25 pressure class rating, translating to a maximum working pressure of approximately 363 PSI. The spiral wound construction combines the spring-like resilience of a metal winding with the conformability of a filler material, creating a robust seal that performs reliably under thermal cycling, pressure fluctuations, and harsh environmental conditions. This gasket is supplied as a convenient pack of ten.
