Description

Cod. 4183

Metalgraf® packing is composed of layers of tape made of flexible expanded graphite twisted into compact threads. Each individual filament is reinforced with a mesh sleeve made of Inconel threads.

It is then treated with lubricating agents to reduce the wear on the shaft and with a corrosion inhibitor to prevent pitting corrosion.
