The Primary Tank Tube Seal design is a liquid filled product, normally water, kerosene or other. The seal design has been used on tanks with different diameters, containing the full range of Crude and Refined products. It has separate Scuffband and Tube. The Scuffband is designed with a ribbed surface and is produced in nylon fabric coated with a hardwearing elastomeric material to withstand contact with the roughest tank shell.
The Tube Seal can be varied in sizes from 250 mm. to 350 mm. depending on the tank size and nominal rim space and it is normally manufactured in one continuous length but can be supplied in separate sections.
For other designs, please head to our Floating Roof Storage Tank Seals page where you can find a range of internal and external tank seals.
