James Walker Gland packing / fat cord with Low Friction Capabilities Lionpak 2101

Pure dry PTFE packing with low friction capabilities
Lionpak 2101 is an interlocked braided packing made of pure dry PTFE fibre yarn. It is non-toxic, contains no lubricants or additives and is a cost effective alternative to Lionpak 2100.
This packing is designed for use in valves as well as in pump applications including centrifugal pumps and rotary equipment and reciprocating pumps and rams.

Prime features

• Very low coefficient of friction.
• Minimal wear on shafts and sleeves.
• Long service-free life, with virtually no volume loss due to chemical action.
• Very little gland adjustment needed after initial installation.

Typical applications
Valves, pumps, mixers, reactors, agitators and extruders, in applications where the low friction characteristics of pure PTFE are required.
Recommended for duties in compressed air systems.

Chemical properties
Inert to chemicals within the range pH 0-14, excluding molten alkali metals, fluorine compounds and aqua regia.
