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:

- Reduced turbulence within the flange area and protects against corrosion or erosion
- Improvement of the load distribution over the gasket
Spiraltherm Graphite S 9584/NF
Spiral wound gasket without guide or inner ring.
This style of gasket is used in load-bearing flange configurations, such as tongue and groove flanges.
Standard dimensions according to EN/ASME.
