Pipe penetration sealing three


Pipes with Axial movement.

WA.GPAM - V1 and V2 axial pipe movement sealing. are dual seat seals, the flex inner boot and pipe seal is watertight to 0.14 MPa Version 1 seals fit inside a the opening, V2 mounts outside the opening.

The carrier pipe passes through the inner seal, mounts inside the wall opening. The flex boot is EDPM, compression plates may be 304L or 316L stainless steel.


- The seal maintains leak integrity up to 1 bar / 14.5 MPa / 20 psi.

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

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

- The unit is not supplied in a split version.

Pipe seals for axial movement - external wall mount

WA-GPAM.V2 pipes with axial movement are dual seat seals, with a flex boot and watertight seal. V2 model seals mount outside a wall or sleeve opening.

The seal absorbs pipe axial movement without violating the integrity of the seal.

The seal flex boot elastomer is EDPM element rubber, the compression plates are 304L or 316L stainless.


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 outer disc seal compresses against the wall. The boot membrane joints the two compression seals.

Application range

- Openings must be 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 water, gases and smoke.

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.

Pipe through wall Seals vibration dampening.

WA.GPKM disc seals are custom units with a 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 flex pipe seals

Annular deflection movement of pipes occur due to differential settlement of structures. WA-GPNS seals allow differential movement while providing watertight Integrity of the seal.

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.

Aesthetic pipe seals polished 316L SS

WA-GPSP pipe seal for pipes that have high visibility in traffic areas.


An extended lip prevents the unit from dislodging in vertical mount applications.

The units are manufactured as a closed model only.

They 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.
