GRAPHITE GLAND PACKING
Graphite Gland Packing is a premium compression sealing material manufactured from expanded graphite fibers, flexible graphite yarns, or graphite-based braided constructions designed to provide reliable sealing in high-temperature and high-pressure environments.
Graphite packing is widely recognized for its excellent thermal conductivity, self-lubricating characteristics, chemical resistance, and dimensional stability. It is commonly used in rotating and reciprocating equipment, including pumps, valves, agitators, and industrial process systems.
Compared with conventional packing materials, Graphite Gland Packing delivers improved sealing efficiency while minimizing shaft wear and maintenance requirements.
