Highlights
- Spiral wound construction with alternating metal strip and soft filler for resilient, pressure-responsive sealing
- Designed for raised face flange connections; self-centering under bolt load
- Accommodates minor flange surface irregularities and variations in bolt preload
- Suitable for oil and gas, compressed air and gas, process piping, and general industrial service
Application
- Raised face flanged connections on production vessels, separators, and process equipment
- Oil and gas flow lines and gathering system piping requiring dependable metallic gasket sealing
- Compressed air, gas, and liquid service on pressurized industrial and oilfield systems
- Standard flange assemblies where a proven, widely specified spiral wound gasket is required
Type SRI
Spiral Wound Gasket
Inner Ring / High Pressure Protection
Designed for higher pressure and critical service, this gasket includes an inner ring to protect against inward buckling and improve sealing stability. Ideal for applications where sealing integrity and bore protection are essential.

Highlights
- Inner guide ring prevents inward buckling and protects pipe bore from gasket intrusion under high bolt loads
- Maintains consistent sealing geometry across high-pressure and elevated-temperature operating conditions
- Designed for raised face flange connections; suitable for critical-service and high-cycle applications
- Preferred specification where bore protection and sealing integrity are both required
Application
- High-pressure flanged connections on production equipment, wellhead assemblies, and process vessels
- Critical-service oil and gas flow lines where gasket intrusion into the bore cannot be tolerated
- Elevated-temperature process piping systems requiring a dimensionally stable, bore-protecting gasket
- Applications where standard Type SR gaskets are insufficient due to high bolt loads or pressure cycling
