Mica gaskets

Mica flat-ring gaskets are suitable for use in high temperature applications.
The gasket can be used at a permanent temperature of 800°C and short-term up to 900°C. The gasket features good medium resistance, gas leak tightness and a low minimum seating stress.
An inner eyelet increases operational safety and cost-efficiency. Heat-resistant steel is used as reinforcement in the form of corrugated ring inserts, eyelets and perforated metal insert.
