Sealing Chain Type LU

Sealing Chain Type LU

Type LU sealing chains are a simple but very effective way of sealing the space between carrier pipes and ducts/casing pipes or holes drilled through concrete walls in buildings.
The sealing chain is made of elements that interlock with each other making a perfect seal.
When fitted and put round the pipe and pushed into the hole and tightened by the bolts, they expand evenly round between the pipe and the hole making a perfect seal.
Sealing chains are used for sealing pipes in the walls of concrete tanks, foundations, swimming pools, pump houses and many other situations, such as cathodic protection of the pipes, noise reduction and for clean rooms. Protection against liquids, fumes, smoke and gases.
Type LU sealing chains can be used to seal pipe diameters from 40 mm to extremely large diameters.
You can seal steel, cast iron, plastic and concrete pipes. LU sealing chains can handle pressures up to 2.5 bars. We recommend using a double sealing chain called 2 LU for pressures up to 5 bars.
