Graphite packing with PTFE corners

Graphite packing with PTFE corners prevents extrusion and delivers reliable sealing for high-temperature, high-pressure .....


Graphite Packing with PTFE Corners is a composite sealing packing designed to combine the excellent thermal and chemical resistance of graphite with the extrusion resistance and low friction properties of PTFE. The PTFE-reinforced corners effectively prevent graphite extrusion under pressure, while the graphite body ensures tight sealing and stable performance at elevated temperatures.

This balanced construction allows the packing to perform reliably in both dynamic and static applications, especially where high temperature, high pressure, and chemical exposure are present.
