Graphite Coated PTFE Filament Yarns Braided in a Multi-Lock Construction with Aramid Corners

Manufactured from true filament, not a folded tape or ribbon, most commonly associated with other PTFE and graphite composite packings. Each filament (approx. 400 per yarn) is layered with graphite offering better heat conductivity and faster shaft speeds.

This unique layered process of graphite and filament yarns results in 38% less thermal expansion than other PTFE yarns producing more uniform pressure on the pump shaft or sleeve. The corners are made of an aramid filament yarn to reduce extrusion and increase pressure and strength.
