TorrLid® 297

A highly specialised compression packing used for crucible lid seals at higher temperatures.

  • Crucible lids

TorrLid 297 is a highly specialised product that features a resilient, hollow-centred elastomeric core that resists higher temperatures than the ethylene-propylene used in TorrLid 162B. The core is over-braided with a jacket of filament glass yarns, and the exterior surface is then coated with a proprietary graphite dispersion.

  • Developed as a higher temperature vacuum seal for the lids of crucibles as used in specific aluminium smelting plants
  • Readily withstands the temperatures and compressive forces involved
  • Withstands repeated opening/closing cycles

This well-proven product is used as a vacuum lid seal for crucibles containing liquid / smelted aluminium. It is particularly popular with aluminium plants in the southern hemisphere.

  • Static duties with crucible lids
  • Maximum working temperature: Suitable for holding a vacuum over liquid / smelted aluminium in crucibles, please contact us for further advice
  • Pressure range: from partial vacuum up to 0.9 MPa/9 bar (131 psi)

Manufactured to order, in a wide variety of sections and lengths, to meet customer specific requirements.
