Durlon® CFG (Corrugated Metal Core)

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.


  • 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



Durlon® Durtec® (Premium Corrugated Metal Core)

Application:  The Durtec® gasket is designed to withstand high temperatures and pressures, to be blowout resistant, to be fire safe, and to resist toxic and/or corrosive chemicals. The design of the Durtec® gasket also makes it an excellent choice for tough to seal cyclical pressure and temperature applications. Durlon® Durtec® gaskets have a much lower leakage rate as compared with spiral wound type gaskets under conditions of the same loading stresses. They provide excellent sealing performance and safety after installation and are an excellent choice to replace spiral wound gaskets.

​The Durtec® Advantage

  • Fire Safe- SS316L/Graphite Passed Modified API 607 fire test
  • Blowout Resistant- Metal core provides excellent resistant to internal pressure spikes
  • Reusable – On larger sizes and for special configurations, the core may be refaced with new material and reused providing lower cost of ownership
  • Superior Core Technology- Durtec® design can allow for complete replacement of spiral wound and Kammprofile gaskets with improved performance and lower life cycle cost
  • Easy and safe to handle, easy to install
  • Seals tightly with lower bolt loads vs. spiral wounds and kammprofiles
