The World's only Flange Rescue Gasket

The Flange Rescue Gasket (FRG) enables bolted joints to be easily and effectively sealed to prevent internal corrosion. The soft SIGMA®inner ring of the FRGs conform seamlessly to the flange face, even if already damaged to:

  • Save you time and reduce lost production
  • Provide a major cost saving when compared with replacing flanges, welding and  machining
  • Gets you back up and running within a day

  • Flange Rescue Gasket (FRG)

    • Restructured Sigma® PTFE bonded to a precision machined metallic core providing a leak free seal and blow out resistance.
    • High visibility, corrosion resistant PTFE coated metallic body with integral bolt holes to aid identification.
    • Highly compressible Sigma® 606 to conform to flange face corrosion damage, to seal and prevent further deterioration.
    • Superior mechanical integrity allows the use of the full range of torque reducing the risk of operator error or failed repair
    • Flanges can easily be inspected and sealed effectively enabling fast, accurate assessment on internal corrosion.
  • Fire Safe

    A fire-safe solution for use by engineers dealing with corrosion damaged flange faces, in challenging environments, such as hydrocarbon containing systems.

    • Using Thermiculite®, our high temperature insulating, fire resistant material, the FRG-FS is certified to API 6FB providing assurance of its integral fire-safe nature together with the ability to seal damaged flanges
    • FRG-FS has been subjected to, and passed, the stringent and essential API 6FB fire test which involves testing the gasket in its entirety, not just components.
  • High Pressure

    We developed the FRG-RJ for applications utilising high pressure ring type joints. RTJs are used extensively in the oil and gas industry due to the gasket’s longevity and high pressure resilience, however, ring joint flanges are the most common area for leaks, typically due to corrosion.

    • Stops turbulent media flow to prevent erosion, corrosion and flange degradation.
    • Available in Style R Oval, R Octag, RX, SRX.
  • Subsea

    In response to engineer demand for a Flange Rescue Gasket for sub-sea use, and analysis of the challenges of this environment, we adapted the FRG with additional functionality to promote safe practice in this environment.

    • Incorporation of an additional identification handle allows easy installation for deep sea divers; the patented snap feature can be left on, or if required can be easily removed.
    • FRG- SS has all the benefits of the standard FRG - anti corrosion, easy installation, sealing for damaged flange faces, reduced maintenance, adapted for sub-sea use.
    • Incident prevention and easy sub-sea installation with integrated, removable handle.
  • HF Alkylation

    Engineers responsible for critical service applications now have access to the unique benefits delivered by the Flange Rescue Gasket range with the FRG-HF.

    • Developed for applications where highly aggressive chemicals are used such as Hydrofluoric Acid in alkylation processes.
    • FRG-HF provides the ultimate sealing potential in reducing corrosion activity with the ability to seal already corroded flanges in maintenance operations.
    • Combines the low stress sealing of the fully structured modified Sigma® along with the fire safe graphite faced serrated metal core.
    • FRG-HF developed for usage in onshore fire safe environment, sealing flammable media under pressure, and was further developed for use in alkylation plants.
    • Fire Safe for corrosive chemical service, especially alkylation applications.
    • Ease of identification with problematic connections.
  • Cryogenic

    In response to demand for effective sealing in LNG and cryogenic service applications, we developed the FRG-CS.

    • Metallic core of the FRG-CS manufactured from aluminium as standard - can be adapted to match the flange/connection alloy, ensuring the materials expand and contract at the same rate, delivering a superior sealing solution.
    • The FRG-CS features the unique Sigma® core which adapts to the flange face, even when already damaged, to provide excellent sealing potential, preventing corrosi
    • Applications include Liquefied Natural Gas production facilities.
    • PTFE ring allows use of FRG-CS in temperatures ranging from 260°C to Cryogenic Service
