Composition
Pure mineral flexible graphite high Carbon content
Features
GR48 is braided with pure flexible graphite strands.
Applications
Packing specific to seal all kind of industrial valves working with all fluids and gases, except the strong oxidizers. Avoid combustion gases and hot air over 450°C. The valve’s pressure has to be under 100 bar if the packing is not assisted by high pressure wiper rings. GR48 is suitable also for dynamic applications if assisted by harder wiper rings.
