Durlon® mica-graphite filled spiral wound gaskets are made with graphite filler layers surrounded by pure mica filler layers. This construction method enhances gasket performance in many ways without the added expense of special filler materials offered by competing brands.
- Pure mica layers protect graphite from rapid oxidation at high temperatures up to 760°C (1,400°F)
- Mica offers enhanced fire protection
- Maintains original ASME B16.20 “pink strip” filler marking
- Eliminates the need for many high temperature and high cost special gaskets
