Nickel Wire Outer Hook-braided Flexible Graphite Braided Packing
This external hook-braided nickel graphite packing is braided from pure graphite yarn, with each yarn reinforced by an Inconel wire mesh and enhanced with a blocking agent. Chemically stable, soft, easily formed, well lubricated and highly conductive, it will not harden and is inert to chemicals, with no risk of extrusion or deformation at high temperature and consistent leakage control for high-temperature, high-pressure valve sealing. Suitable for all media except fuming sulfuric acid, fuming nitric acid and aqua regia.
