Overview
This 321 Stainless Steel Graphite Spiral Wound Gasket is engineered for reliable, long-term sealing in demanding industrial flange connections. It is constructed using the spiral wound method, which combines alternating layers of metal winding and resilient filler material to create a seal that compensates for flange irregularities, thermal cycling, and system pressure fluctuations. This specific configuration is designed for high-temperature and high-pressure service across a wide range of chemical and process applications.
Key Features
Constructed with a 321 stainless steel winding for superior stress corrosion cracking resistance
Features a flexible graphite filler for excellent thermal conductivity and conformability Spiral wound design provides a resilient, spring-like seal that maintains integrity under variable loads
Suitable for use in both indoor and outdoor service environments Non-paintable surface ensures material integrity is not compromised
