Anti-oxidation Nickel Wire Outer Hook-braided Flexible Graphite Braided Packing
The anti-oxidation external hook-braided nickel graphite packing is made from specially treated graphite tape with each outer surface reinforced by an Inconel wire mesh, braided into a dense yet soft packing. Surface-treated with lubricant to reduce rod friction, it is chemically stable, easily formed, well lubricated and highly conductive, will not harden and is inert to chemicals, with no risk of high-temperature extrusion or deformation and consistent leakage control. Suitable for all types of high-temperature, high-pressure valve sealing.
