Pilotpack 8500

Description

PILOTPACK 8500 has been designed for very high-temperature valve, slow rotating and static applications. Each strand of the high-temperature BCX yarn is impregnated with a high-temperature lubricant and additional mechanical strength provided by high-temperature nickel alloy wire reinforcement.

The resultant packing is dense, firm and uniformly lubricated with a low coefficient of friction.
It is designed for use in rotary, reciprocating, valve and static equipment, across a range of product applications, but specially designed for hot air and gases up to a maximum temperature of 750˚C.

Applications

  • Designed especially for use on hot air and gases.
  • Suitable for use on slow rotating equipment.
  • Ideal for sealing high temperature ducting and exhaust manifolds.
  • Designed to operate across a full range of equipment.
  • Easy to install and manufactured to give long operating life.

Chemical Compatibilities

For the pH range 3-13, the packing is chemically inert. For steam applications, please consult Beldam Crossley.

Sizes Available

All square sections from 3mm (1/8”) to 25mm (1”) are generally available from stock and supplied in differing lengths depending on the cross-section. Larger and rectangular sections can be manufactured to order. Packing can also be supplied in preformed or die formed rings.
