Bridas anti-filtración KG

Wall collar KG

The wall collar provides a fast and easy way to lead pipes through wall penetrations in walls and base tiles.

The elastomer collar made of high-quality EPDM rubber is moved onto the middle of the pipe and fixed with two tightening straps on each side of the collar flange by tightening the turnbuckles.

If the different expansion coefficients of the wall and the carrier pipe result in a gap and water pours in due to capillary action, the wall collar will be there to interrupt and stop the route of the water.

The carrier pipe equipped with the wall collar is shuttered and grouted. These pipe penetrations are tight against pressing water.
