PART NUMBER ANALYSIS

To properly select or replace this material

Sheet Composition and Properties

The Flexitallic SF 2401 PDS327 Rev3 datasheet describes an aramid/NBR sheet. For a 1.5 mm thickness, the manufacturer lists 8% compressibility, 48% ASTM recovery, and a density of 2.0 g/cm³. It indicates availability in thicknesses from 0.5 to 5 mm and in 1,500 × 1,500 mm sheets. An older product family brochure shows different values, highlighting the importance of requesting the specific applicable datasheet version.

Documented Industrial Applications

SF 2401 is a general-service compressed fibre gasket material designed for water, steam, gas, oils, and mild chemicals within the published operating envelope. The ratings of 350°C and 100 bar represent individual maximum limits and do not constitute a combined operating point.

Replacement Selection and Considerations

Do not assume interchangeability with SF 2400 or other aramid/NBR sheet materials. Steam operating parameters, media compatibility, and bolt torque requirements remain specific to the referenced version. Thoroughly evaluate flanges, cut gaskets, thickness, seating face conditions, and project engineering documentation requirements.

Cross-reference candidates: Flexitallic SF 2400 and TEADIT NA1001. Technical equivalence must be verified.
