Product variants
Spiraltherm Mica 9596/GA
Spiral wound gasket with outer guide ring.
Standard type for raised faced flanges.
Spiraltherm Mica 9596/GIA
Spiral wound gasket with inner and outer guide ring offers the best performance in raised faced and flat flanges
The inner ring is used to:
- avoid over-compression at elevated seating loads in high pressure service
- reduce turbulence within the flange area and protects against corrosion or erosion
- improve the load distribution over the gasket
Spiraltherm Mica 9596/NF
Spiral wound gasket without guide ring 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.
Spiraltherm Mica 9596/VR
Spiral wound gasket without inner ring or outer guide ring.
Mainly used for male and female flanges or projection and recess flanges.
Spiraltherm® Glimmer 9596/VRI
Spiralthermdichtung mit Innenring.
Hauptanwendung sind Flansche mit Vor- und Rücksprung.
Um die Stauchung der Dichtung zu regulieren, ist diese Variante nur mit Innenring einsetzbar.
