SPIRAL WOUND GASKETS
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.
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.Get a quote
Suitable for use with flat face and raised face flanges and specified for high pressure/temperature service or where corrosive or toxic media are present.Get a quote
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.Get a quote
RING TYPE JOINTS (RTJ)
Ring type joints excel in high-pressure, high-temperature applications such as oil field drilling equipment. RTJs are also used on valves and pipework assemblies.
Available in both oval and octagonal configurations (interchangeable on the modern grooved flange). Standard ring type joints are manufactured to meet both API 6A and ASME B16.20 sizes and ratings.
The Style BX ring type joint is manufactured in accordance with API 6A. All BX ring type joints incorporate a pressure passage hole to allow for pressure equalization each side of the sealing faces. On assembly, metal to metal contact of the flange faces is achieved. The Style BX is not interchangeable with any other style, and is only suited for API 6BX flanges. Style BX ring type joints are designed to seal pressure up to 20,000 psi in accordance with API 6A pressure ratings.Get a quote
The Style R ring type joint is manufactured in accordance with API 6A and ASME B16.20, to suit API 6B and ASME B16.5 flanges.
Style R ring type joints are manufactured in both oval and octagonal configurations. Both styles are interchangeable on the modern flat bottom groove, however only the oval style can be used in the old type round bottom groove.
Style R ring type joints are designed to seal pressure up to 6,250 psi in accordance with ASME B16.5 pressure ratings and up to 5,000 psi in accordance with API 6A pressure ratings.Get a quote
The Style RX ring type joint is manufactured in accordance with API 6A and ASME B16.20, to suit API 6B and ASME B16.5 flanges.
Style RX ring type joints are manufactured in both oval and octagonal configurations. Both styles are interchangeable on the modern flat bottom groove, however only the oval style can be used in the old type round bottom groove.
Style RX ring type joints are designed to seal pressure up to 6,250 psi in accordance with ASME B16.5 pressure ratings and up to 5,000 psi in accordance with API 6A pressure ratings.Get a quote
FLANGE RESCUE GASKET (FRG)
Across the compliance spectrum, from health and safety, through environmental issues to incident avoidance, the FRG is a cost saving revolution.
This corrosion management tool is both proactive in helping inspection and reactive in enabling repair. By reducing leaks and slowing corrosion the possibility of shut-downs with associated HSE visits are dramatically reduced, as is the huge loss of revenue associated with a stop in production.
- 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.
Sigma pairs the outstanding chemical resistance of PTFE with enhanced dimensional stability.
Developed for processes ranging from cryogenic temperatures to 500ºF (260ºC), and suitable for sealing virtually every chemical medium across the entire pH range (0-14). Sigma range materials contain non-stick properties that aid in an easy removal process after their usage to dramatically reduce the downtime on shutdown.
Now available in 80 x 80 sizes.

The Change heat exchanger gasket is incredibly robust and resilient, and is designed to deliver the most dynamic seal ever.It’s manufactured with proprietary equipment, using a 5-times thicker metal spiral and a unique laser welding process that penetrates completely through. As a result, it requires no inner or outer ring, and is as easy to handle and install as a double-jacketed gasket. Furthermore, it’s proven to perform without fail at least 60% longer than any other heat exchanger gasket, spiral wound, double jacketed, CMG, or Kammprofile.
