Lionpak® 5505 datasheet

Low friction graphite moulded rings for low torque valve operation.

Lionpak 5505 is a graphite moulded ring packing that represents a major enhancement to the operational capabilities of graphite sealing rings used on valve stems.

The rings are precision moulded from high purity expanded graphite foil to which a special low friction coating has been sinter bonded. This 5 μm thick coating is sinter bonded to the expanded graphite before the moulding process to ensure maximum service life.

Lionpak 5505 is typically used on valves that handle dry gases and other fluids, where friction on standard graphite seals is unacceptable high as well as valves that suffer judder, hesitation or erratic action due to carbon pick-up or high-spot friction on the spindle.
