Filler
Graphite for industrial gaskets
Flexible graphite filler with excellent thermal stability and chemical resistance — the preferred facing and winding filler for heat-resistant gasket service.
Flexible graphite is the benchmark filler for demanding steam and hydrocarbon service. A flexible graphite gasket keeps sealing through repeated thermal cycles that would harden or crack lesser fillers, which is why it is the default choice inside spiral wound and Kammprofile gaskets for oil & gas, petrochemical, and power plant flanges.
Key properties
- Excellent thermal stability
- Good chemical resistance
- High compressibility and recovery
- Ideal filler for high-temperature service
Typical gasket uses
- Spiral wound gasket filler
- Kammprofile facing
- Corrugated gasket facing
- Jacketed gasket filler
Frequently asked questions
Why is graphite preferred for high-temperature gaskets?
Flexible graphite maintains sealing performance across a wide temperature range and recovers well under thermal cycling, making it a preferred filler for steam and high-temperature process service.
Is a flexible graphite gasket suitable for high-pressure steam?
Yes. Flexible graphite is one of the best fillers for high-pressure, high-temperature steam service, which is why it is the standard filler recommendation for spiral wound gaskets on critical steam and power plant flanges.
