James Walker Gland packing / fat cord Graphite Reinforced with Inconel® Lionpak 5202

Pure dry PTFE packing with low friction capabilities
Lionpak 5202 is an economical packing made of expanded high purity 99% graphite fibre reinforced with a single Inconel wire in each strand.
The packing is reinforced with Inconel wire and is impregnated with James Walker’s proprietary graphite-based dispersion to enhance sealability, and further treated with a corrosion inhibitor.

Lionpak 5202 is designed for use in valves, has excellent chemical resistance and is easy to cut, shape and install.
