Graphite gaskets specifications
Material type: Expanded graphite
Operating pressure: up to 250 bar (depending on design)
Temperature range: −200 °C to +450 °C (up to +550 °C in non-oxidizing environments)
Creep resistance: excellent
Sealing performance: highly reliable under extreme conditions
Graphite gaskets offer outstanding sealing performance in high-temperature and high-pressure applications. They are commonly used in flanges, valves and heat exchangers where fibre or PTFE gaskets are no longer suitable.
