Wall Sleeves General

Wall sleeves with extended flange connections

Wall Sleeves with extended flange connections: WA-WS.F units, have connection flanges extending out from the wall for connecting pipes through the wall. The sleeve is cast in during wall construction. ANSI 125# or ANSI #150 flat face flanges or raised face may be used.

wall-sleeve-flange-connectWA-WS.F double flanged wall sleeves may be grouted in as a retrofit in an existing wall or cast in a new wall.

Wall sleeves for pipes are available for any wall thickness and pipe diameter.




Wall Sleeves Stainless steel




The pipe sleeve flange extends out from the wall for a bolt, washer nut connection and may be a full pipe length or a shorter wall piece.

Stainless steel, carbon steel, galvanized or corrosion protected coatings are available.

Wall Sleeves WA-PF-KS units are custom units with customer defined measures. The end flanges are stabalization flanges to ensure a round sleeve structure. Mainly used for large pipe diameters or thick wall structures.



WA-PF-KS units cast in wide concrete walls, or are used when large diameter pipe penetrations are required. WA- pipe seal links fill the annular space between pipe and sleeve to form a watertight passage.

A puddle flange is mounted in the middle of the sleeve as a waterstop and anchor point.

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


The flush end flanges fit inside the wall form boards.

Wall Sleeves WA-ZVR models are non-metallic wall sleeves. Water and gas tight applications for conduit, power cords, communication cables or pipe through concrete and block walls.

A special bonding coating creates an homogeneous bond with new concrete or grout resulting in a 72 psi (5 bar) passage for pipes and conduit through structure walls.


The special bonded pipe sleeves, attach to the concrete - preventing leaking around the sleeve. End caps insure a clean passage is maintained until pipes are ready to enter the building.

Pipes / Conduit pass through the sleeve into a structure and are sealed with Pipe Mechanical Seals. The seals are provided as part of the assembly based on the conduit or pipe size entering through the foundation.

multi-conduit-sealing-building-entryCompression seals, model WA-GPSR pipe seals may be used with the WA-ZVR wall sleeve. They allow single penetrations or multiple pipe / conduit to pass through the same opening.

The cement bonded pipe sleeve can be set in concrete or block walls.


Watertight up to 72 psi, 5 bar
Pipe diameters from 3 inch to 12 inch (80 to 300 mm)
Suitable for any type of wall

Wall sleeves entering at an angle through the wall


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

The same approach angle of the pipe is maintained, eliminating additional bends in the pipeline.

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


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.

There are many configurations available.

Multi-conduit wall penetration sleeve seals provide wall openings for several conduit and cable entry ports into a building. The sleeves may vary in size for different size conduit or pipe.

The sleeves are water and gas tight. The penetrations are sealed with disc mechanical seals.

For multi conduit penetrations through an existing wall, an opening in the wall is cut or sleeved to accommodate the size required.

There are several combinations of multi-conduit sleeve seals. For the best suited units for your project, please contact Westatlantic tech Corp.

Minimum spacing wall sleeves allow close together multi pipe penetrations through concrete walls.

WA-WS-BW temporary passage wall sleeve.


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.
