Durlon 8900 Aramid-Graphite/NBR

Durlon 8900

Durlon 8900 is a premium grade compressed non-asbestos sheet gasket material for service conditions to 496°C (925°F) and continuous operating temperatures of –73°C to 400°C (-100°F to 752°F), or 13.8 MPa (200 psi). It is suitable for saturated and superheated steam, oil, dilute acids and alkalis, hydrocarbons and solvents. DURLON® 8900 has achieved the requirements of the Fire Test Certification ANSI/API 607, 6th Edition with zero leakage.

Note: ASTM properties are based on 1/16” sheet thickness, except ASTM F38 which is based on 1/32” sheet thickness. This is a general guide only and should not be the sole means of accepting or rejecting this material. The data listed here falls within the normal range of product properties, but should not be used to establish specifications limits nor used alone as the basis of design.
