When you need a sealing solution that can stand up to superheated steam and tough chemical service, the 8900 gasket material is engineered to deliver consistent performance in demanding industrial environments.
At Gasket Resources Inc. (GRI), we focus on practical, field-proven sealing solutions informed by customer feedback, hands-on engineering support, and continuous improvement across real-world applications.
Introducing Durlon® 8900
Durlon® 8900 is a premium-grade compressed non-asbestos sheet designed for high-temperature service and challenging media. It’s well-suited for saturated and superheated steam, oil, dilute acids and alkalis, hydrocarbons, solvents, and refrigerants.
- Maximum service temperature: 925°F
- Continuous operating range: -40°F to 752°F
- Pressure capability: up to 2000 psi (application dependent)
- Coating: proprietary anti-stick coating to support clean installation and easier removal
Why the 8900 gasket material performs in superheated steam
Superheated steam is a challenging environment because high temperature and low moisture can accelerate gasket degradation and limit the effectiveness of some conventional materials. In applications where equipment design, cycling conditions, or gasket geometry makes alternatives less practical, Durlon® 8900 provides a dependable option for high-temperature sealing.
In boiler house service, Durlon® 8900 was evaluated in superheated steam turbine applications (400 psig with 725°F superheated steam) over extended testing. Following successful results, it was applied in additional steam turbine service and hot air dryer applications operating at 165 psig and 600°F superheated steam.
The performance characteristics are supported by an aramid/inorganic fiber system with very low binder content and graphite filler, combined with an NBR rubber binder. In stress relaxation testing, the material demonstrated low relaxation values over 16 hours at elevated temperatures, helping support long-term sealing stability.
