DURLON® CFG
CORRUGATED FLEXIBLE GRAPHITE GASKETS
ASTM F868: 9FMF2 (F104: F517000-B1M3)

APPLICATION:

DURLON® CFG is a corrugated, flexible graphite gasket material designed for severe service conditions.  The proprietary design of the corrugations gives CFG superior sealing and recovery characteristics for tough conditions in the refining, chemical, petrochemical and pulp and paper industries. DURLON® CFG is suitable for service in steam, oil, water, mild alkalis, mild acids, hydrocarbons and solvents.

COMPOSITION:

 DURLON® CFG consists of flexible graphite laminated both sides to a corrugated stainless 316 core.

AVANTAGES:

   Fire Safe:

  • Passed a modified API 607 fire test at Southwest Research Institute.

   Blow-Out Resistant:

  • Metal core counteracts internal pressure spikes.

   High Spring-Back:

  • Excellent recovery in thermal cycling and severe vibration services.

  • Stable leakage control with minimal force.

   Superior Emissions Control:

  • DIN 3535 gas permeability/leakage:
    <0.01 cc/min

   Seals Imperfect Flanges:

  • Flexible graphite fills small voids

   No Inward Buckling:

  • Corrugations force the flexible graphite up to the sealing surface

  • No expensive inner rings required

   Seats on a Variety of Surface
   Finishes:

  • 60 to 750 rms

   Easy & Safe to Handle, Install and
   Remove:

  • Will not cut

  • Large gaskets easily install, will not collapse, fold or unwind

  • When replacing, cleaning flange serrations is unnecessary

   One Thickness for All Applications:

  • Reduces gasket inventory

  • Standardize installation procedures

Warning: Durlon gasket materials should never be recommended when both the temperature and the pressure are at the maximums listed.  Properties and applications shown are typical.  No application should be undertaken by anyone without independent study and evaluation for suitability. Never use more than one gasket in one flange joint, and never reuse a gasket.  Improper use or gasket selection could cause property damage and/or serious personal injury.  The data reported is a compilation of field testing, field service reports and/or in-house testing.  While the utmost care has gone into publishing the information contained herein, we assume no responsibility for errors.  The information and specifications  contained in this website are subject to change without notice. This revision cancels and obsoletes all previous editions.
