Flexitallic SIGMA® 588

Sigma 588 is specifically designed for use in flanges where only low bolt loading is available. Such flanges can be glass lined,
ceramic, plastic or be so distorted that they include areas of low gasket stress. Suitable for sealing all chemicals across the
whole pH range (0-14) with the exception of molten alkali metals and fluorine gas. Consisting entirely of pure PTFE, this material
is suitable for use with hydrogen fluoride.
