Expanded Flexible Graphite Gland Packing GR48

Expanded Graphite Gland Packing GR48

Features

The expanded graphite gland packing GR48 is braided with pure flexible graphite strands. GR48 is the greatest solution to make seal's ring for pumps and valves.

Composition

100% pure flexible expanded graphite yarns high Carbon content.

Applications

The compression packing expanded graphite GR48 is 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.
