SIGRAFLEX® Standard flat gasket

Sigraflex Standard is a homogeneous flat gasket made of flexible, high-quality expanded natural graphite that provides a reliable seal without binders. The sheet is impregnated, which improves handling and reduces leaks. Unreinforced yet robust, it is ideal for flat sealing strips, enamel or glass flanges and for use with highly corrosive media. This innovative solution provides an effective seal and is particularly adaptable.
