Gland Packing
Nickel Wire Reinforced Flexible Graphite Braided Packing
This graphite packing is braided from graphite yarn and reinforced with Inconel wire for mechanical strength. It retains the good properties of graphite packing — chemical stability, good lubrication, extremely low friction and high thermal conductivity — and is widely used for high-temperature, high-pressure valve sealing. Suitable for pumps, turbines, general and high-temperature valves, and all ordinary valve assemblies and steam valve systems.
