Area of use
The Wall Collar system sealing joint is used for tight tubular ducts that pass through aprons or walls.
The sealing joint is pressure-tight up to 8 bar and approved by the TÜV; it prevents outer-wall moisture from infiltrating the pipe.
The Wall Collar system sealing joint comes with two special steel strips. The circular collar provided with additional water blockers prevents liquids from infiltrating the shell.
Where the sealing joint is applied to the pipe, and after tightening the special steel strips, small water blockers seal for a water column up to 50 m'.
