Graphite packing ปะเก็นเชือก ผงดินสอ หรือ ปะเก็นเชือก graphite

Expanded graphite packing is braided from high-grade low sulphur expanded graphite yarn. This item has superior resistance from high temperature and chemical corrosion, as well as other special sealing effects. It's widely used in steam valves of powder station, , static sealing with high temperature, high pressure and chemical corrosion.
