BPG 9451
Properties
BPG 9451 Corrugated Metal Gaskets (CMG) are constructed from a corrugated stainless steel insert with flat graphite foil layers applied to both sides. This design combines strength with flexibility, providing excellent resilience and reliable sealing performance under varying operating conditions.
Applications
Due to its high compressibility and good resilience, BPG 9451 is suitable for thermal cycling conditions in petrochemical, oil and gas, process, chemical and power plant industries, especially for heat exchangers, pumps, valves and compressors.
