Pipe penetration sealing three


Pipe Penetration Disc Seals

Pipe penetrations though in visible settings - Polished Stainless finish WA-GPSP disc units


floor-seal-for-pipe-passage WA-GPSP pipe seal for visible pipes.

WA-GPSP units are used where the pipe is exposed outside a wall in a visible environment. The seal fits on floors and ceiling. Materials are polished 316L for cosmetic effect.

An extended lip prevents the unit from dislodging into an opening.



The units seal against water, gas and smoke migrations through floors and ceilings. 

Fireproof materials may be used to fill the space between the seals to create a fireproof penetration.concrete-slab-seals-pipe-through-slabs-floors





WA-GPSP pipe seals provide sealing for small or large pipes.




The advantages :

Pipe through wall Seals for vibration isolation.

WA.GPKM disc seals are custom units with a double seal: an inner and outer seal.

Vibration noise is absorbed by cushioning elastomer. Complete tightness up to 2 bar / 29 psi /67 ft head. Elastomer may be EDPM or NBR. Diameter range: up to DN 3000 / 120-inch pipe.










The seal cannot be supplied in a split configuration for existing pipe. Maximum flex is +/- 40 mm.

Sounds and vibration that travel along pipes through wall structures are effectively dampened. The double seal design isolates and insulates contact between the pipe and the opening.

Advantages: Vibration compensation

Max working pressure: 2 bar / 29 psi / 0.2 MPa
Compression Plates: 304L – 316L
Sealing elastomer: EPDM, NBR
Working temperature seal elements:
EPDM (-30 ° C - + 100 ° C)
NBR (-20 ° C - + 90 ° C)
Noise transmission is diminished along the pipe.

Pipe deflection - Seal integrity -WA-GPNS seals:

Pipe seals - Movement between structures - watertight - watertight flexing pipes

Annular deflection of pipes may occur due to differential settlement between structures. WA-GPNS seals allow differential movement but watertight Integrity of the seal is maintained.

The pipe opening size must be at least 120 mm more than the pipe OD. The max opening size is limited to 300 mm (12 inch).


The dual seal flexible design compensates for shear stress of 10-12 mm.

Compensating seals maintain a 1.5 bar / 22 psi hydrostatic Integrity even when deflection occurs.

Elastomer may be: EDPM, NBR or Silicone.


WA-GPNS seals may also be used in single pipe penetrations as well as opposing structures where the seal is installed on both sides.

For example soil stress may cause a pipe to move but the structure remains constant.

Sealing pipe that have Axial movement

WA.GPAM -V1 axial seals: are dual seat seals consisting of a boot flex seal and compression seals.

The carrier pipe passes through the inner seal, the outer seal is positioned inside the wall opening. The rubber boot provide a flex joint between the two compression seals. The seal rubbers are EDPM.



- The seal maintains leak integrity up to 1 bar / 14.5 psi / 33 ft. water column.

- Pipe sizes up to 20 inch pipe (500mm).

- Axial movement of +/- 50 mm of pipe movement can be absorbed.

- The unit does not supplied in a split version.




Larger cores or wall sleeve openings must be allowed for WA-GPAM sealing.

Pipe seals for axial movement - external mount

axial-pipe-expansion-sealingWA-GPAM.V2 is an external wall mount seal.

The seal absorbs pipe axial movement without violating the integrity of the seal. It mounts outside the core or wall sleeve opening.


The WA-GPAM.V2 pipe flex seals are not manufactured in a split version for existing pipes.

The carrier pipe passes through the center seal, the seal compresses to the outside wall. The boot membrane joints the two compression seals.

Application range

- Openings must larger to allow for flex movement of the pipe.

- Sealing pressure 0.1 MPa (14.50 psi). Pipe diameters up to 20 inch / 500 mm.

- Pressure sealing for pipes, conduit and cables penetrating through a concrete wall.

- Seals against Liquids, Gases and Smoke.

- Allows axial movement and annular deflection of the pipe. Reduces Vibration.

Scope of delivery: seal elastomer, pressure plates, anchor bolts for external wall mounting.


Pressure plates - corrosion resistant stainless steel 304L or 316L.

Rubber: EPDM: -30C - +100C.

Tightness: Tight to 0.1MPa
