Tankatite® 440

Suitable for all types of vessel and International Maritime Organisation (IMO) classes.

  • Tank lids

Tankatite 440 is a 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 lids as well as those with rougher surface finishes

Suitable for bulk liquid cargoes in all International Maritime Organisation (IMO) classes, this product is commonly used in the sealing of tank lids, main hatches, inspection and cleaning covers on tankers and chemical barges.
