PRODUCT
BRIEFING

Lionpak® 5201 / 5202

Product capability

• Expanded, high purity graphite-based packing with metallic reinforcement
• High pressure capabilities up to 300bar (4351psi)
• Multiple wire reinforcement (Lionpak 5201) enhances the mechanical strength of the

packing to resist pressure surges
• High temperature capabilities up to 450°C (842°F)
• Both products have FE capabilities although have not been certified to any FE standards -

very good sealability and low leakage is very important in steam applications as it helps to
reduce the cost of steam leakage (relatively expensive media)

Application Industry

• General purpose valve stem handling • Power Generation

Performance

Product construction / design

Expanded graphite fibre with 99% minimum purity, reinforced with inconel wire and
impregnated with high temperature, graphite-based dispersion to enhance sealability.
Lionpak 5201 - each yarn is reinforced with multiple inconel wires (min 2 for smaller section
and max 5 for bigger sections). Due to such construction (highly reinforced) it can be used
in steam lines in thermal power plants in case of pressure surge (pressure fluctuation).
Lionpak 5202 – each yarn is reinforced with single inconel wire hence suitable for steam
application at continuous pressures (with no pressure surge).
