PART NUMBER ANALYSIS

To properly select or replace this material

Key Features of This Construction

Carbon fibres are the defining technical feature of this grade. The manufacturer publishes process-tailored thermal ratings; however, the presence of carbon alone does not guarantee suitability for all operating temperatures.

Key Criteria for Selecting a Replacement

For steam service, distinguish between continuous temperature, peak temperature, and pressure. Specify any thermal cycling as well as the plant's intended bolt-torque sequence.

To compare constructions: Garlock High-Temp 9850 and TEADIT NA1100. Fibres, binders, and potential reinforcements vary. Verify the exact material construction prior to any substitution.

KEY COMPARISON CRITERIA

Durlon 8300 is a carbon fibre/NBR compressed sheet, not a homogeneous flexible graphite sheet. Durlon 8900 incorporates graphite fillers into an alternative formulation.
