Product variants
Spiraltherm Graphite 9584/GA
Spiral wound gasket with outer guide ring.
Standard type for raised face flange connections.
Spiraltherm Graphite 9584/GIA
Spiral wound gasket with inner and outer guide ring. This style offers the best performance for raised-face flange connections.
The inner ring is used to provide:
- Avoid over-compression at elevated seating loads in high pressure service
- Reduced turbulence within the flange area and protects against corrosion or erosion
- Improvement of the load distribution over the gasket
Spiraltherm Graphite 9584/VR
Spiral wound gasket without inner ring or outer guide ring.
Mainly used for male and female flanges or projection and recess flanges.
Spiraltherm Graphite 9584/VRI
Spiral wound gasket with inner ring.
Mainly used for male and female flanges or projection and recess flanges.
An inner ring is necessary as a compression stop.
