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 if sealing is required.

When longer sleeve lengths are required, former ribs are placed along the sleeve length as required 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.

Split wall sleeves, KS models, for existing pipes come with weld up seams or bolted closings.

Engineered wall sleeves prevent deformations that may occur during concrete pouring. They are available for all pipe sizes.

Two basic measure requirements for pipe sleeve sizing are:

Outside diameter of the pipe going through the wall sleeve.
Thickness of the concrete wall determines the length of the sleeve.

Fiber Cement Wall Sleeve for Concrete wall or block wall construction.


Asbestos-free, corrosion-resistant fiber-cement wall sleeve are installed for pipes through walls, ceilings or floors.


Fiber cement wall sleeves are also used for new walls, or mortared in wall sleeves. Split, or two half wall sleeve sections are used when pipes already exist.

With an outside groved surface, concrete grout fusing occurs, forming a completely no leak around sleeve.

Fiber cement wall sleeves do not require a smooth core hole and may be place and grouted into a square or hammered out wall passage. Pipe passing through the sleeve are sealed water tight with a modular seal.

The opening may house a single pipe or several pipe penetrations and sealed with a single LPS Link seal or multi pipe Disk seal.

Flanged flush mount 316 stainless wall sleeves with Puddle Flange waterstops.

WA-EL-1 wall sleeves are cast in the wall flush with the wall forms or shutters, forming a flanged connection 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 reservoirs in particular, and are used in other applications. Water treatment plants, concrete tanks, clarifiers and tunnel connections, with flush mount requirements may also use cast in WA -EL sleeves in 316, 304 or galvanized sleeve materials.

WA-EL wall sleeves when used with a blind flange provide openings for future pipe passage.

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.
