Lionpak® 2303

A reliable packing based on graphite and PTFE yarn with silicone‑free lubrication.

TYPICAL APPLICATIONS
  • Pumps
  • Valves

Formerly known as Liongraf, Lionpak 2303 is a highly reliable pump and valve packing based on graphite and PTFE yarn that is thermally stabilised then lubricated with a silicone-free compound.

Sections of 6.5 mm (1/4") square and above are of cross-plaited construction; sections below 6.5 mm are plaited.

  • Strong, durable and extrusion resistant
  • Reliable over a wide range of duties
  • Excellent chemical resistance
  • Low friction with high thermal conductivity

Widely regarded as an economical packing for universal application and the reduction of stockholding requirements. Well proven in the petrochemical, power generation, marine and metallurgical sectors, and by pump and valve manufacturers for OEM installation. It is suitable for duties with steam, condensate, effluents, fuels and oils, acids, alkalis and chemical solutions.
