Lionpak® 9600

A non‑hazardous fibre packing for very high temperature applications.

  • High temperature
  • Rotary equipment
  • Static sealing

Formerly known as Valcor Hi-Temp, Lionpak 9600 is a compression packing for very high temperature duties.

It is manufactured from an exceptionally stable fibre material that is soft, non-irritating, non-hazardous, and is not limited by World Health Organisation or European Union restrictions.

The yarn is spun into a flexible yarn and with low percentage of glass fibre and Inconel wire reinforcement. It contains no organic agents or processing additives. It therefore retains its physical and chemical properties at very high temperatures and does not decompose into hazardous substances.

A cost effective alternative is also available, please download the Lionpak 9603 datasheet for full details and specification.

  • Non-hazardous heat resistant fibre construction
  • Alternative for normal ceramic fibre packings
  • Good chemical compatibility

  • Recommended for very high temperature static sealing duties or slow rotary applications
  • It replaces ceramic yarn packing and radiation seals on BOS plant, and ceramic packings and vessel lid seals on secondary steelmaking plant
  • Other examples include door seals for annealing furnaces at steelworks, kiln packings, protective surfaces on pottery kiln cars, and stem gland sealing on valves handling very high temperature gases
  • Other constructions include braided insulation sleeves, webbing tapes, ladder tapes, twisted ropes, lagging ropes, blankets and paper, and woven cloth

Static and Slow Rotary Duties Only

  • Maximum operating temperature (constant): +1000°C (+1832°F)
  • Maximum operating temperature (intermittent): +1100°C (+2012°F)
  • Minimum working temperature: -50°C (-58°F)

Compatible with media in the range pH 0 -10, excluding hydrofluoric acid and hydrogen fluoride. It has excellent resistance to water, organic chemicals and other acids.

  • Available as densely braided compression packings - square, round and rectangular - in sections from 5 mm (8/16") to 100 mm (4") and in any length 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
  • Please refer to the product datasheet for spool ordering information
  • Other constructions are manufactured to order

  • Average diameter of the mineral fibre used is 9 μm (354 μin), which is considered non-hazardous to health. No protection for breathing, eye, hand or body is required by the World Health Organisation or European Union during the product’s normal storage, handling and use.
  • For further details please contact us to request a copy of our Safety Data Sheet (SDS). Please note that normal ceramic fibres, as often used in the manufacture of very high temperature compression packings, are around 3 μm (118 μin) in diameter. These much finer fibres are now considered hazardous to health, with WHO and EU restrictions applied to the products that contain them.

  • Classified as non-carcinogens according to the criteria of note Q in European Directive 97/69/EC
