Wall Sleeves - Pipe Sleeves with Puddle Flanges

Steel Cast In Wall Sleeves

Westatlantic Class solutions for pipe entry and sealing.

Wall Sleeves for Large Pipes: Long length sleeves.



Steel wall sleeves model WA.KS for large pipe passage. Galvanized steel or stainless steel (304L or 316L) materials.

Lengths up to (10 ft.) 3000 mm


Applications: wall sleeves and ducts for large pipes, penstock flues.

Rib forms provide strength, ovality and anchor points. The former ribs also provide Puddle Flange waterstops which prevent water creep along the outside of the Wall Sleeve.

Where sealing is required for large pipes use WA.KS wall sleeves.

With WA.KS wall sleeves, use modular seals for large pipe sealing: GKD Models. WA.GKD models offer optimum torque feed back information to the installer during placement.

Westatlantic Class KS wall sleeves for large pipes are used in thick concrete foundation walls, underground tunnels, wind turbine foundation slabs and dam structures.


WA - Stainless steel or galvanized steel wall sleeves with puddle flanges. The puddle flange is welded both sides for maximum corrosion resistance, waterproofing and strength.


Cast in Wall Sleeves are available to form openings for all pipe sizes requiring waterproof entry through concrete walls or slabs.

Modular link sealing c/w the assembly to seal the annular space between the pipe and the sleeve.

Westatlantic stainless steel (304L or 316L) wall sleeves offer maximum corrosion resistance.

WA. Split Wall Sleeves - Split Pipe Sleeves for existing pipes

All American and International pipe sizes

Split wall sleeves are bolt closed or a weld closed.

split-wall-sleeve-existing-pipeWA.-Split pipe sleeves are used when new concrete walls or slabs are placed across existing pipes.

Split pipe sleeves models are bolt closed or a weld closed. Standard split sleeve lengths are 12 inch long and sized to accommodate the diameter of the existing pipe. Longer sleeves are available.

The number of puddle flange collars on the sleeve, depends on the length of the sleeve.

Bolt close models come with a flange design, plus bolt closing hardware.

Weld closing models come with beveled axial splits for welding. Split disk compression seals or modular seal links are supplied with the split sleeve assembly.

When longer sleeve lengths are required, former ribs are placed along the sleeve length for anchoring and to insure ovality of the sleeve.

Wall sleeve diameters allow annular space best suited for the modular seal. Depending on length of the pipe sleeve, a second puddle flange may be attached to the assembly.

WA-EL-1 wall sleeves are cast in the wall flush with the wall forms or shutters.

WA-EL-1 forms a flanged connection at the wall for continuing pipes. Acorn nuts allow the fasteners to be imbedded in the concrete between the wall shutters.

(Flange to Flange Connection)


WA-EL-1 flush mount wall sleeves come with a puddle flange (wall collar), that prevents water creep along the sleeve.


WA-EL-1 316 stainless wall sleeves are use for portable water tank concrete structures in particular.

They may be use in water treatment plants, concrete tanks, clarifiers and tunnel connections.

Pipe wall sleeves for pipe through walls at an incline.


WA-PD-KP pipe sleeves for walls or floor slabs are use when pipes pass through a concrete structure on an angle. Tapered ends and angled puddle flange waters stops, are matched cut to the pipe entry angle.

Angled wall sleeves allow pipes to pass through concrete walls on a straight axial line, eliminating additional bends. Incline pipe sleeves come has a split model if pipes already exist.

A GP seal for angled pipe sleeves, creates a 36psi watertight passage - up to 80ft. head of pressure.

For installation, extended bolting make accommodations for the degree of incline.

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

Sealing elements may be EDPM, NBR for hydrocarbon applications or silicone for heated pipes.


WA-GP-T external wall mounted pipe sleeves.

External Wall Mount / Slab mount / Thimble pipe sleeve seals

Bolts to the wall or slab seals to the wall and pipe.



WA GP.T pipe sleeves and seal assembly is designed for external pressure sealing pipes and cables. They may be installed for pipes through manholes, slabs, concrete walls, building foundations or floors.







The assembly is comprised of a sleeve and back plate for fastening to the wall. The back plate is sealed at the wall. A link type annular seal, or disk seal, seals the pipe watertight.

Disk seals are used when more than one pipe is passed though the sleeve. The back plate may be round or square.


A thimble wall sleeve may be split for existing pipes and may be angled to accommodate incline conditions. see samples below.

For Several pipes through the same wall sleeve, GP.T disk seals may Conduit-seal-cable-pipe-through-metalseal-conduit-building-entriesaccommodate several pipe through the same sleeve opening.. Use Split Disk-seal grommet seals, for conditions where the pipe or conduit is already in place.

Various Configurations for Wall Sleeves with flange plate bolting.

Off Center pipe - Centered pipe- Incline pipe - Angle Intercept pipelines.





Supplementary Products. for Wall sleeve sealing

Sealing elastomers for single pipe penetration, multi pipe penetrations through the a single sleeve, small annular space seals, off center pipe seals.



WA-GP Disk seals are used if more that one pipe or conduit passes through the same sleeve, or when the pipe is not centered through the Wall sleeve.
