Wall Sleeves - Pipe Sleeves with Puddle Flanges

Cast In Wall Sleeves

Westatlantic Class solutions for pipe passage through concrete walls. 'Multi-Pipe Non-Corrosive Through-Wall Sleeve System'.

Flush mount 316 stainless wall sleeves with Puddle Flange and end connector flanges.

WA-FF-WS wall sleeves are cast in the wall flush with the wall forms or shutters.

WA-FF-WS with flanged connections at the wall allow continuing pipes through the concrete walls. Acorn nuts attached to the flanges allow pipes to be connected. Flanges may be attached to the wall sleeve on both sides or one flange and an open end combination.

(Flange to Flange Connection)


WA-FF-WS flush mount wall sleeves have a puddle flange (wall collar), that prevents water creep along the sleeve and is an anchor point for the sleeve.


WA-FF-WS stainless wall sleeves are used in WWTP plants, water treatment facilities and water tanks. Wallsleeves for flange connections are also available in other steel materials.





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

Wall Sleeves for Large Pipe diameters.



WA-KS-1 wall sleeves are recommended for large pipes that penetrate through concrete walls. Long sleeve lengths are available with multiple puddle flanges along the pipe sleeve, for added strength and ovality.

Materials are galvanized steel or stainless steel (304L or 316L) materials.


Lengths up to 10 ft. (3000 mm) are available.

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

Former ribs prevent water creep along the outside of the Wall Sleeves.

For large pipe diameters use modular seals for large pipe diameters, WA- GKD Models. WA.GKD modular 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.

WA-GKD modular seals are design for thick concrete foundation walls, underground tunnels, wind turbine foundation slabs and seal through dam structures.



WA - KS ll single puddle flange wall sleeve materials are stainless steel or galvanized steel. Standard is 304 stainless, 12 inch long. 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 pipes. Using a Westlatlantic class pipe modular seal for a complete waterproof pipe entry..

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

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

Integrated puddle flanges, provide waters top and anchor point features for the sleeve.

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.

Split wall sleeves come with two or more puddle flange collars on the sleeve.

Bolt closing 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.

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.

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.
