To combat the effects of pressure and temperature fluctuations, flexibility and recovery are essential.

The Flexitallic spiral wound gasket is the precision-engineered solution for flanged joints, heat exchangers, boiler handholes, manholes, and other high-temperature, high-pressure applications—providing resistance to virtually every known corrosive and toxic element.

  • Thermiculite® 835 Spiral Wound Gasket

    • High temperature filler material for spiral wound gaskets
    • Termperatures up to 982ºC / 1800ºF
    • Class 150 to 2500
  • Style CG

    Utilizes an external ring which accurately centers gasket on flange face: provides additional radial strength to prevent gasket blowout and acts as a compression stop. A general purpose gasket suitable for use with flat face and raised face flanges.

  • Style CGI

    For use above class 600, this gasket is a Style CG gasket with an internal ring for an additional compression limiting stop. For use with flat face and raised face flanges, this gasket features increased compressive force for blow-out prevention and is specified for high pressure/temperature service or where corrosive or toxic media are present.

  • Style R & RIR

    This spiral wound gasket is a sealing element only – controlled compression must be in the flange. Inner and outer diameters are reinforced with several plies of metal, without filler, to give greater stability and sealing. All other SWG’s (except Style R and HXRIR) have compression built into the gasket.  We also offer Style R Spiral Wound Gasket which is fitted with an inner metal ring.

  • HF Alkylation

    A Style CGI gasket developed further with metal reinforced graphite (MRG). The CGI-MRG has a metal core laminated with a conformable sealing material. The solid metal provides strength and rigidity also preventing blow-out. The soft facings give an exceptional seal at relatively low gasket stress. Face material and core thickness can be tailored to the application, and a wide range of core materials are available.  Please contact us for more information.

    Baker GasketThe Baker Gasket offers the reliability of a spiral wound gasket with PTFE to prevent acid attacking bolts, plus an emissions containment system. Originally developed for refinery alkylation units, the Baker Gasket features and in-built early warning system for potential hydrofluoric leaks. Any HF acid leaking from the flange travels through an integrated channel in the gasket to the pan-handle which is coated in HF reactive paint – a highly visible indicator for potential leaks.

  • Heat Exchangers

    The gasket features an inner ring which can be manufactured in a variety of materials eg. Thermiculite® dependent on the media. Designed specifically for heat exchangers, the Style HX-RIR gasket is most commonly specified for shell and tube heat exchangers with a TEMA flange.

  • Emission Control

    Low Stress
    The style LS spiral wound gasket has been engineered by Flexitallic to provide an alternative to sheet gaskets in Class 150 and Class 300 service. Style LS gaskets have the inherent strength, resiliency and blowout resistance of spiral wound gaskets, yet require low bolt load for seating. They are manufactured with high purity Flexicarb flexible graphite filler or PTFE filler for optimum sealability, and are available for the full range of standard Class 150 and Class 300 flanges, as well as other non-standard low pressure flanges. The LSI features an additional inner ring for secure sealing and increased blow-out protection with high temperature and chemical resistance, therefore reducing maintenance costs.

    Low Emission
    The Flexitallic Low Emission gasket is a high performance spiral wound gasket that has been specially engineered to exceed stringent oil and gas industry fugitive emissions requirements, such as those found in the Chevron Fugitive Emissions Test (CFET). Independent testing in accordance with the CEFT protocol has show that Flexitallic Low Emission gaskets comfortable exceed allowable fugitive emission leakage levels.  Leakage testing of ASME Class CGI spiral wound gaskets in accordance with the PVRC ROTT procedure shows that Flexitallic Low Emission gaskets require significantly lower bolt stress to achieve a T3 tightness class.
