PART NUMBER ANALYSIS

To properly select or replace this material

Material Construction and Performance

The expanded structure delivers optimal surface conformity even under low gasket seating stress. KLINGER also publishes significant compressibility values that must be evaluated against actual field installation conditions.

Key Verification Points Prior to Material Substitution

When replacing gaskets on fragile flanges, confirm the allowable bolt torque, surface flatness, process media, and gasket width. Never automatically substitute this expanded PTFE with a rigid, filled sheet.

To compare material configurations: Durlon 9600 and TEADIT 24SH. Expanded PTFE is available in various structures and densities. Always verify bolt load conditions and flange geometry.

KEY COMPARISON CRITERIA

Soft-chem differs from the filled-PTFE top-chem 2000, 2003, and 2006 products, which are engineered for application-specific performance based on individual formulations. Expanded PTFE should not be confused with mineral-filled PTFE.
