A highly specialised compression packing used for crucible lid seals at higher temperatures.
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.
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.
Manufactured to order, in a wide variety of sections and lengths, to meet customer specific requirements.
