Compression Packing

Tankatite and TorrLid

The complete package for tank, crucible and furnace door sealing applications.

Tankatite and TorrLidTankatite
Our comprehensive range of tank lid packings developed to meet the increasingly stringent international regulations that cover the maritime transport of chemical and potentially hazardous cargoes. Extensions to the range cover the requirements of road and rail transport, plus static or mobile tank containers.

Torrlid
A specialised high-temperature product designed for high temperature static duties such as crucible lids in metal smelting applications and the sealing of furnace doors.


Tankatite 250

Tankatite 250A state of the art packing design specifically developed for production in rectangular sections and at smaller sections to suit the smaller tank lid recesses of road and rail tankers.

  • Easy to cut and fit in small section lid recesses
  • Tough, resilient and long-life product
  • Withstands repeated opening/closing cycles
  • Controls emission levels from tanks
  • Protects tank contents from contamination
  • Withstands arduous cleaning systems

Typical applications are seals to fit the smaller tank lid recesses of road and rail tankers.

Tankatite 440

Tankatite 440A resilient elastomeric core, spirally wrapped with PTFE tape and surrounded by successive braided jackets of inert polypropylene yarn. Specially reinforced corners are incorporated to build the section to the required packing size. The braided structure is spirally wrapped with further layers of PTFE tape to provide an impermeable barrier to liquids and gases, then finally enclosed in a robust, abrasion resistant braid of PTFE yarns.

  • Gas-tight environmental seal
  • Protects cargo from sea water ingress
  • Withstands repeated opening/closing cycles
  • Unaffected by steam and other tank cleaning systems
  • Suitable for smooth recesses in stainless steel lips as well as those with rougher surface finishes.

Typical applications are sealing of tank lids, main hatches, inspection and cleaning covers on tankers carrying all known bulk liquid cargoes in all International Maritime Organisation (IMO) classes.

Tankatite 660

Tankatite 660A heat resistant grade of Tankatite. Similar in construction to Tankatite 440, but with braided jackets of high quality glass fibre yarns instead of polypropylene.

  • Gas-tight environmental seal for heated cargoes
  • Protects cargo from sea water ingress
  • Withstands repeated opening/closing cycles
  • Unaffected by steam and other tank cleaning systems

Typical applications are seals for tank lids that cover heated cargoes, such as molten bitumen, which need to be transported at elevated temperatures to prevent solidification in the tank.

Tankatite 880 ACR

Tankatite 880 SuperA new economical grade of general purpose lid packing for tank containers, road and rail tankers, especially where the packing needs to be changed after each trip/cargo. It is a white packing constructed from spun acrylic fibre yarns impregnated with PTFE suspension. Dense but flexible, it is easy to cut and fit,
and to remove when it needs to be replaced.

  • Excellent value for money
  • Contains no grease or oil - no lubricant to squeeze out when packing is compressed
  • Easy to cut and fit in small section lid recesses
  • Easy to remove when it needs replacing
  • Protects tank contents from external contamination
  • Approved, specified and used by major tank container operators world wide

Typical applications are seals for lids and fittings on tank containers for road, rail or static use that contain chemicals, petroleum products or foodstuffs. This general purpose lid packing for tank containers, road and rail tankers, proves invaluable when the packing needs to be changed after each trip/cargo.

Tankatite 880 Super
Tankatite 880 SuperA clean, length form packing manufactured from an inert reinforced polypropylene yarn, impregnated with PTFE and an inert resin to provide a non-stick surface. It contains a resilient elastomeric core for improved performance.

  • Excellent value for money
  • Equivalent performance to moulded rubber seals
  • Easy to cut and fit in small section lid recesses
  • Excellent sealing capability on repeated opening/closing cycles
  • Controls emission levels from tanks
  • Protects tank contents from external contamination
  • Withstands arduous cleaning systems

Typical applications are seals for lids and fittings on tank containers for road, rail or static use, that contain chemicals, petroleum products or foodstuffs. Also for lids and fittings on dedicated tanks that handle aggressive cargoes under an inert gas blanket. It readily replaces moulded rubber sealing components and low cost packings.

Torrlid 162B

Torrlid 162BThis specialised product has been developed specifically as a lid seal to hold a vacuum within crucibles of molten aluminium. It features a resilient hollow-centred core of ethylene-propylene elastomer, over-braided with a jacket of filament glass yarns. The exterior surface is coated with a layer of red-coloured silicone rubber.

  • Developed specifically as a vacuum seal for aluminium crucible lids
  • Readily withstands the temperatures and compressive forces involved
  • Tough silicone rubber coating provides abrasion resistance
  • Withstands repeated opening/closing cycles

This exceptionally well-proven product is used worldwide as a vacuum lid seal for crucibles containing molten aluminium. It has also proved a great success on new plant using the latest AP35 technology.

Torrlid 297

Torrlid 297This highly specialised product 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 molten aluminium. It is particularly popular with aluminium plants in the southern hemisphere.
