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.

Developed for processes ranging from cryogenic temperatures to 500 Degrees F (260 Degrees C), and suitable for sealing virtually every chemical medium across the entire pH range (0-14), Sigma pairs the outstanding chemical resistance of PTFE with enhanced dimensional stability. Sigma range materials contain non-stick properties that aid in an easy removal process after their usage to dramatically reduce the downtime on shutdown.
