Packing of expanded pure graphite yarn reinforced with a thin inconel wire. Due to its thermal and chemical resistance, self-lubricating properties and good thermal conductivity, the expanded graphite is perfect for high temperature braided packings. Use of reinforcement a with thin inconel wire improves mechanical strength of the packing, while preventing it from entering into the gap between a shaft or a spindle and an enclosure of the stuffing box.
Recommended for use in stuffing boxes of pumps and fittings at extremely high temperatures, with water, steam, oils, solvents, salts, acids and alkalis, with exception of strong oxidants. Not recommended for use with liquid metals, e.g. iron, and abrasive media. Particularly popular in professional power generation sector.
