For more than 15 years, Projex Group has been working with designers, engineers, project managers and contractors in specifying and supplying Link-Seals into water and waste treatment plants, desalination plants, oil refineries, gas plants, hospitals, sewage plants throughout Australia.

Link-Seal® Modular Seals are a positive hydrostatic seal that seals the annular space and is considered to be the premier method for permanently sealing pipes of any size passing through walls, floors and ceilings.

Link-Seals are a robust product and are specially formulated to withstand attack from ozone, UV, water, hydrocarbons and a wide range of chemicals.

Link-Seals are also available for a wide variety of special applications, temperature extremes, exotic chemical combinations and for slightly “out of round” or non-centered applications.

Pipe seals for a wide range of applications
Site engineers and maintenance contractors prefer Link-Seals:
  • If a leak occurs at any time in the future due to excessive pipe movement, the Link-Seals can be tightened to stop the leak
  • If at any time in the future the pipe needs to be removed it is only a matter of loosening the Link-Seals
  • If another pipe of the same diameter as the original pipe is then installed the original Link-Seals can be re-used to seal the penetration
  • The Link-Seals allow for minor pipe axial movement without breaking the seal
Installation times have been reduced to up to 70% whether it was new works, a retrofit situation and during “Maintenance Shutdowns".
