Wall Sleeves Flange to Flange Pipe Connection

Stainless steel wall sleeves - Pipe through wall connections


Wall Sleeves WA.WS-FF units mount flush for a pipe flange connection through a concrete wall. The stainless steel wall sleeves are provide with ANSI flanges on both or one end for connections.


A steel puddle flange attached to the sleeve forms a waterstop and anchoring point for the sleeve. The units cast in a new concrete wall to provide a continuous passage for the pipe penetration.

Protected Hex nuts, female thread rod or studs provide seating for connection bolts.

All American and International pipe diameters may be accommodated.


Wall Sleeves WA-WS-FF stainless sleeves are used in WWTP, water treatment facilities, water tanks and other applications for pipe penetrations..

Diameter range: up to 60 inches (DN 1600)


Stainless steel: 304L-316L, schedule10s or schedule 40 or metric sleeves are available.

Wall Sleeves General

Pipe sleeve double flange joint

Wall Sleeves for pipes: WA-WS.F units, are extended flange units for the connection of incoming flanged pipes.

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

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



Wall Sleeves Stainless steel




A continuous transition of the pipeline through the wall is accomplished

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

Carbon steel and galvanized wall sleeves also available.

Wall Sleeves WA - PF units for wide concrete walls, or large pipe penetrations.wall-sleeves-for-large-pipes


Wall sleeves WA-KS-1 units allow large diameter pipes or wide walls sleeves to pass through walls. Plain end collars are mounted on each end. A puddle flange is mounted in the middle of the sleeve.

Wall-Sleeve materials are stainless steel (304L & 316L) - Lengths up to 10 ft. (3000 mm) are available.

Applications: WA.KS-1 units form duct sleeves for large pipes, penstock water pipes and wide wall penetrations.

Puddle flanges at the midway point prevent water creep along the outside of the wall sleeves into the structure, end flanges form part of the sleeve. The end flanges fit inside the wall door forms and are flush with the concrete wall.

Pipe passing through the sleeves are made waterproof by using modular seal links suited for large diameter pipes.

WA-modular seal links are designed for larger pipe penetration sealing. WA.GKD modular seal links are an advanced design seal for large pipe projects. They provide high pressure watertight solutions for all large diameter pipes and large diameter wall sleeve combinations. Contact Westatlantic Tech Corp..


Underground tunnels, wind turbine foundation, floor slabs and dam structures are applications where WA-GKD modular seal links are used in combination with the larger wall sleeves.

Multiple pipe seals through the same sleeve opening are also available for large diameter wall sleeves.

Split wall sleeves for pipe may be bolt closed or a welded closed.

Split wall sleeve provide a wall opening when a new concrete wall or slab is placed around existing pipes. They can mount horizontally or vertically.

Standard split sleeve lengths are 12 inch long and sized with an inside diameter that allows mechanical seal links or disc seals to waterproof the pipe penetration.

Split wall sleeves for pipe are available for walls greater than 12 inch or less that 12 inch.

The annular space between pipe and sleeve are sealed with mechanical seal links. Other sealing forms may be requested by the customer.

Two puddle flange collars are standard on the split sleeves. They ship with bolt closing hardware, EDPM flange gaskets and pipe seals ready to install.

EDPM, NBR or Silicone sealing elements may be selected for sealing the pipe.

Double pipe watertight sealing - Multi pipe watertight sealing

Multi - port openings WA-GP-W models are used when more than one pipe or conduit penetrates through the same sleeve.



Split WA-GP-W sleeves are also available, for existing pipes.


Wall Sleeves WA-ZVR models: are cast in a new concrete wall providing a water and gas tight entry points for pipes, conduit, cords and communication cables.

The special bonding coating create a homogeneous bond with new concrete resulting in a 72 psi (5 bar) passage for pipes and conduit through structure walls.


Cement bonded pipe sleeves, bonds with concrete - providing no leak around solutions. 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 Modular Seals links, or WA-GP-SR disc seals. The seals are provided as part of the assembly.

Wall sleeves for pipe through walls on an angle


Wall sleeves WA-A-PD units provide openings for pipe passage that enter a wall at an angle. Angled ends and puddle flanges are angled to fit perpendicular in the wall.

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


Angled pipe wall sleeves may be split units for pipes that already exist and new concrete walls are built across the pipes.

Pipes sleeves that allow pipe to penetrate a wall at an angle use long bolt WA-GP disc seals that have long bolt tighteners. The seals are 36 psi watertight pipe seals, for possible pressing water up to 80 ft. head.

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 when new walls or slabs are placed over the pipe.

Sealing elements may be EDPM, NBR or Silicone for heated pipe applications.


Wall sleeve seals external wall mounting units model WA-EW-WS are fixed to an outside wall.


WA-EX-WAT split wall sleeves, seal a pipe penetration from outside the wall.


Leaking link seals from a previous installation are repaired using a WA-EX-WS, the pipe remains in service while the leak condition is repaired.

A gaskets seals the collar against the wall and a pipe seal is used to seal the annular space between the pipe and the "T" sleeve.
