High carbon content flexible graphite yarns.
GR48 is a high-quality expanded mineral graphite packing made of high carbon content expanded graphite yarns. Its ability to withstand extreme temperatures and high pressures, combined with low thermal conductivity, make it an ideal choice for many industrial applications, where ease of cutting and installation is combined with extraordinary versatility. Thanks to its high-quality construction and great reliability, the expanded mineral graphite packing GR48 is a winning choice for those looking for a versatile and high-performance product for their industrial needs. Additionally, GR48 packing is also available in the reinforced version GR48R.
The flexible mineral graphite packing GR48 is an ideal solution for sealing industrial valves of all types, thanks to its extreme flexibility and versatility. Due to the high carbon content in the expanded graphite yarns, this packing is able to resist multiple industrial fluids and gases, with the exception of strong oxidizers. It can operate at a maximum pressure of 100 bar without the use of anti-extrusion rings. In the case of dynamic seals, however, it is recommended to use it with the help of anti-extrusion rings to ensure even better performance and extend its lifespan.

Never use the product to the maximum temperature and pressure associated. Consult the manufacturer for further information
The peak temperature can be sustained for short exposures
With weakly oxidizing agents and hot air the temperature must be limited to 450 ° C
With steam and non-oxidizing fluids the temperature must be limited to 650 ° C
Graphite and carbon cannot be used with oxidizing fluids
The packing shall be used with wiper anti-extrusion rings with dynamic applications and with those in valves over 100 bar
