Angled Wall Sleeves / Pipe penetrations through concrete walls

WA-angled WS


Wall sleeves WA-angle units provide openings for pipe passage at an angle through the wall. Angled sleeve ends and angled puddle flanges fit perpendicular to the sleeve.

The approach angle of the pipes are maintained through the wall. Additional bends in the pipeline are reduced.

Angled pipe wall sleeves may be split for pipes that already exist.


Pipe penetration at an angle through concrete wall sample drawing

Angled wall sleeves use longer compression bolts and WA-GPSR disc seals. Disc seals are watertight mechanical pipe seals.

Split wall sleeves for existing pipe, are available with either weld closings or bolted closing. They are available for most pipe sizes and accommodate existing piping for a new wall.

Sealing elements may be EDPM, NBR or Silicone.
