Supagraf HD Pro is a high temperature / high pressure multi‑layer high grade graphite sealing system.
Supagraf HD Pro is a high grade TA-Luft approved gasket sheet made of multi-layer stainless steel and highly oxidation-resistant flexible graphite. The layers of graphite and stainless steel sheets are laminated with a high strength non-adhesive joining system. The impregnation of the sealing layers reduces leakage and improves handling.
