Graphite with PTFE Impregnated Gland Packing
Graphite Packing with PTFE Impregnated is braided from Expanded graphite yarns which impregnated with PTFE as a blocking agent thus creating a non-straining packing. The yarns are reinforced by textile fibers.
Excellent cross-section tightness, structural strength
Very lo friction-valve, wear resistant, yet gentle to shaft and stem.
