Plain end form support collars are mounted on the ends of each sleeve. A puddle flange is mounted in the middle of the sleeve.

Wall-Sleeve materials may be stainless steel (304L, 316L or anti corrosion coatings. Lengths up to 10 ft. (3000 mm) are available.


Puddle flanges at the midway point prevent water creep along the outside of the wall sleeves. The flush end flanges fit inside the wall forms.

WA-modular seal links are designed for larger pipe penetration sealing. Modular seal links are an advanced design seal for large pipe waterproof sealing. Torque announcer windows form part of the new design in waterproof sealing.

Multiple pipes may be sealed through the same sleeve opening using multi port disc seals.

The sleeves have a fixed flange on the weather side and a loose flange fitted to the inside wall.

The inside flange is loose so it may be fixed to the wall and a silicone seal bead is placed around the pipe and sleeve after the loose flange is anchored to the wall.

Both flanges have a EDPM wall gasket.




Wall sleeves for block Walls

temporary-building-entry-wall-sleeve WA-FL-BW wall sleeves may be used for pipe passage through a block wall. Pipe or conduit passes through the sleeve and is sealed with a disc mechanical seal.

WA-FL-BW pipe sleeves may also be used through a core opening in a concrete wall when a core drill and a sleeve are required.

The fixed flange on the wall sleeve is fastened to the outside wall and the loose flange is placed on the inside wall. Both flanges have gaskets that fit between the flanges and wall.

The loose flange final finish uses a fillet bead of silicone between the sleeve and flange.
