Pipe Connector boot seals WA-WGC stainless units seal pipes 1 inch to 10 inch diameter / DN25-DN250


Cut sheet for WA.WGC

Flexible pipe connector boots are external seals that fasten against the wall.

The pipe is cuff clamped with a stainless steel band to form a complete waterproof pipe pentration 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 cuff seal in one piece construction, no joints. pipe-seal-boots

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


  • WA-WGC Seals allows radial and axial pipe movements.
  • Seal pipe thought walls from an outside the wall.
  • Elastomers: EPDM or NBR material.
  • Gas tight - Water tight
  • Temperature range -20°C to +110°C
  • Pressure plates and strap bands are 304L stainless steel
  • For concrete walls, or tank walls: supplied with all materials, ready to install.

WA.WGC - external wall pipe connectors
For American and International pipe sizes.


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

They are thick wall rubber seals, 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.

The boot may be split for existing pipes.

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.


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.

Boot seals for tank drains

Pipe drain 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 pipes through a core opening.

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


sewer-pipe-seal WA-ZWS seals are used 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.

Plug seals - Seal pipe and conduit through Bulkhead - Plate - Tanks

Materials: EDPM - VITON - NBR


Pipe Plug Seals are tapered units that seal cables and pipes passing through concrete walls, deck plate and bulkheads. Water and gas tight seals.

WA-expansion plugs are pressured into a sleeve opening or core opening. The profiled design of the seal makes installation easy and ensures a 3 bar (40 psi) tightness.

Plugs are manufactured from high quality rubber and are resistant to abrasion. They are supplied with different rubber types to ensure suitability for all industry and marine applications.

pipe-plug-throught-wall-waterstop Sealing Plugs are applicable to the ship building industry, and are installed from both sides to seal pipe penetrations through a welded sleeve, a wall or deck.

Fire resistance silicone disk seals, are also available providing 60 minutes resistance. A passage sleeve may be further fire proofed with addition materials.

The plug can be used in a core drilled hole or wall sleeve. The plug is pressured into the annular space around the pipe.


  • 60 minutes fire retardant (A60)
  • Resistant to gas, water and pressure
  • Large range of sizes available
  • No special tools necessary for installation
