1. Superior sealing performance compared to asbestos products. 2. Little differences in performance from cyrogenic to high temperatures. 3. Expanded graphite (Graseal) has chemical resistance properties second only to PTFE, and can be used with almost any fluid (with the exception of those listed below). 4. Less shrinkage at high temperatures than asbestos packings, with little stress relaxation.
