Lionpak® 5300

A premier quality graphite packing for valves with corrosion inhibitors.

  • Valves

Formerly known as Grafpak, Lionpak 5300 is a dense, high strength packing of cross-plaited premier quality graphite filament yarns.

Treated with pure graphite before and after plaiting, and further treated with corrosion inhibitors.

A cost effective alternative is also available, please download the Lionpak 5303 datasheet for full details and specification.

  • Suitable for a wide range of aggressive media at elevated temperatures
  • Low friction for low torque valve action
  • Tough and resistant to fretting and extrusion

  • Control valves and main stop valves on high temperature / pressure steam circuits at power stations, chemical plants, industrial services, and on marine installations
  • Also suitable for duties with water, condensate, alkalis, acids, solvents and most chemicals

Valve Stem Duties

  • Maximum operating temperatures:
    • Steam: +550°C (+1022°F)
    • Oxidising conditions: +550°C (+1022°F)
    • Non-oxidising conditions: Significantly higher, please contact us for further details.
  • Minimum operating temperature: -50°C (-58°F)
  • Maximum system pressure (typical): 15 MPa/150 bar (2175 psi)
  • Please contact us for details on higher pressure duties.

Compatible with media in the range pH 0-14, excluding strong oxidising agents.

  • All popular square sections from 3 mm (1/8") upwards, in boxes containing 8 m (26' 3"), in coil form or on spools as detailed in the product datasheet
  • Also supplied as split preformed rings and sets
