Wall Sleeves WA-ZVR models are non-metallic wall sleeves. The provide watertight 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.

Download data sheet:

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
Form an homogeneous bond with concrete
Suitable for retrofitting in core drills and/or rectangular block size openings

Pipe through walls at and angle

Wall sleeves entering at an angle through the wall


Wall sleeves WA-angle units 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.


Pipe penetration at an angle through concrete wall sample drawing

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.

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

Multi wall penetration sleeves are cast in the wall to provide openings for several conduit, cable, pipe or snow melt PEX pipe entry ports into a building. The sleeves may vary in size for different conduit or pipe diameters. The penetration ports are sealed with disc mechanical seals making a watertight passage.

For multi conduit penetrations through an existing wall, an opening is saw cut or cored to accommodate the size requirements.

There are several combinations of multi-conduit sleeve seals.
