Pipes with Axial movement.
WA.GPAM - V1 for pipes with axial movement are dual seat seals consisting of a flex boot and compression disc seals.
Elastomers are EDPM and compression plates may be 304L or 316L stainless steel.
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 disc compression seals.
- 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 +/- 50mm of pipe movement can be absorbed.
- The unit is 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 wall mount
WA-GPAM.V2 is an external wall mount flex seal boot.
The seal absorbs pipe axial movement without violating the integrity of the seal. It mounts outside the core or wall sleeve opening.
The seal elastomer is EDPM and the disc seal is compression plates are 304L or 316L stainless.
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 outer sisc seal compresses to 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.
Material:
Pressure plates - corrosion resistant stainless steel 304L or 316L.
Rubber: EPDM: -30C - +100C.
Tightness: Tight to 0.1MPa

Pipe through wall Seals dampens and isolates vibration noise.
WA.GPKM disc seals are custom units with a double 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.
Pipe Penetration Disc Seals
Pipe penetrations though wallsor floor slabs in visible settings - Use a polished stainless finish WA-GPSP disc units
WA-GPSP pipe seal for pipes that are visable.
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.
WA-GPSP pipe seals provide sealing for small or large pipes.
The advantages :
- Prevents migration of liquids, gases and smoke, between floors.
- Suppresses noise transfer between floors.
- Allows two degree pipeline flex.
- Cut sheet exposed pipe through floors and ceilings seals.
