Pipe Connector boot seals WA-WGC stainless flex boot pipe seals for small diameter pipes (1 inch to 10 inch diameter / DN25-DN250


Cut sheet for WA.WGC

Exterior wall flexible pipe connector boots are designed for new pipes through walls. The WA-WGC allows flexibility of the pipe.

The boot is clamped with a stainless steel band to the pipe forming a complete waterproof pipe penetration through a wall structure.



WA.WGC flexible boots allow axial and lateral movement of the pipe, they may be installed on flat or curved walls.

The monolithic seal boot forms a wall gasket and a cuff seal in one piece construction, no joints.

WA-WGC-two pipepipe-seal-boots


Multi Flex boots seals allow two or more pipes subject to movement to flex without violating the seal integrity.

The boot is a monolithic elastomer - secured in place by a back compression plate and stainless steel cuff banding strap.

Using a double back flange, WA-WGC units can seal a waterproof wall liner and pipe penetration for dual purpose sealing applications.

A curved back plate allows the seal to mount on round manhole walls to allow pipe flex in ant direction.

For American and International pipe sizes.


Split boot seals waterproof existing pipes and casing.

WA-SBS-boot connectors make pipe to casing end seal connections for different diameter pipes.

Thick wall boot seals, are ideal for applications where back filling is involved. Rubber boots may be up to 6 mm thick, WA-SBS boots provide above ground or underground protection.


If a long wall sleeve is penetrating through a concrete wall, one or several casing spacers are used to support the pipe and hold the pipe in alignment so no stress is carried through to the boot seal.

One end of the wall sleeve will need a stub-out extension for banding the split elastomer boot to the sleeve. Joint strips and close bonding material close the split before the unit is band fasten to each pipe.


Pipe sizes from 2" to 42" may be provided with split weatherproof seals either through a horizontal wall or vertical pipe penetration through a roof structure.

Sewer Tank Boot seals

Pipe seals, WA-ZWS units, are expansion connection boot seals that prevent infiltration and ex-filtration.

sewer-pipe-bootEDPM flex boots with stainless steel cuff clamps and stainless expander clamps seal drain connector into a sewer containment tank.

WA-ZWS units are a one piece flex boot for pipe sizes 3 inch to 12 Inch (80mm - 300 mm). Both lateral movement and axial movement is provided.


sewer-pipe-seal WA-ZWS seals mount on gravity lines from tanks and manhole applications.

Pipe entry boots are easy-to-install, materials are EDPM and 304L stainless steel expander clamps and bands.




WA-ZWS seals advantage:

Angular displacement of the pipe up to 12º in all directions. Linear displacement up to 2" (50 mm).
For American and International pipe sizes.
Sealing units fit pipe 3 inch to 12 inch (DN80 - DN300).
Temperature max. -30°C to +110°C.
Expanding clamps for the manhole core drills and bands for the pipe are 304L stainless steel.

Pipe Plugs - Mechanical

Mechanical pipe seals - Disc expander seals - Modular seal link expander seals.

pipe-flow-stoppers-link-modular- rim-seals

WA-PP pipe plugs with modular rim seal links or disc expansion rim seals.

Non-by-pass or with by-pass are available.

Mechanical pipe plugs are used mainly when longer term work is carried out.

For American and International pipe sizes. Stainless steel or galvanized steel material hubs. EDPM, NBR element seals.

Bolt security expanders may form part of plug to fix the units in place. Mechanical type plugs may be re-used on multiple projects.
