PART NUMBER ANALYSIS

To properly select or replace this material

Sheet Composition and Properties

The SBR binder distinguishes it from the NBR nitrile-based SF 2401. Its property data sheet specifies a compressibility of 7.5%, recovery of 52%, and a density of 1.8 g/cm³. The limits of 400°C and 100 bar are sourced from the general catalogue.

Documented Industrial Applications

SF 2420 belongs to the general service sheet category with an SBR binder. Flexitallic indicates sealing capability for a wide range of chemicals within the manufacturer's operational limits. The temperature of 400°C and pressure of 100 bar represent separate maximum values and do not constitute a combined continuous operating point.

Replacement Selection and Precautions

When replacing an NBR grade with SF 2420, always verify the service media and gasket stress. A similar fiber family does not guarantee equivalent oil compatibility. Inspect the flanges, cut gasket, thickness, sealing surface finish, and project documentation requirements.

Cross-references to evaluate: Durlon 8600 and Garlock BLUE-GARD 3200. Technical interchangeability must be confirmed.
