Waterproof Seals - Multiple or Single Pipe and conduit entry through concrete walls

WA-GP annular space seals provide waterproof seal solutions for pipes and conduit entering a building or manhole. Compression bolts mechanically expands the rubber seal for a watertight penetration.

Annular space seals require a 3 1/2 inches seating space. So can be use in very thin or thick walls The seals are ideal for small diameter pipes and larger diameter pipes through manhole openings or wall openings. Split versions may be used on pipes that are already in place.

 

WA-GPSR annular space split seals waterproof existing pipes.

dis-seal-for-a-existing-pipe

An open version of the disc annular space seal waterproof pipes already in place.

The seals wrap around existing pipes, where small or large annular spaces exist.



For firewall applications: a silicone elastomer may be use with fireproof materials to create a fire wall between structures.


Multi-pipe and conduit sealing through one opening.

WA-GPW annular space seals waterproof multi pipes that pass through walls in the same opening:

disk-sealing-grommets-for-multi-piope-through-a-single-holeMulti pipes are sealed at the same time through the same opening.

Annular space disc seals have stainless steel plates for maximum corrosion protection. Seal elastomer may be EDPM, NBR or Silicone.

Operating pressures to 36 psi (0.25 MPa) (2.5 bar)

Annular space disc seals fit all American and International pipe sizes. Inquiry at:

WA.GPSR units seal single pipes or conduit, through a core drill or wall sleeve opening.

watertight-pipe-seal

Fractional or small diameter pipe sealing is accomplished using WA-GPSR units. The low curvature feature of small pipe diameters require a tight wrap around for watertight pipe through walls.

Large diameter pipes may also be sealed with WA-GPSR-Seals, or when a small annular space exist that other pipe seal types cannot be used.


Annular space seals are used as end seals, for pipe through casing runs. WA-GPSR disc seals fit all American and International sizing.


WA-GPSR split units seal the annular space around existing pipes.

dis-seal-for-a-existing-pipe

WA-GPW split pipe and conduit seal wrap around existing pipe and mechanically expanded to seal the annular space between the pipe and opening.

Split disc seals may be installed without taking the pipe out of service.

The inner opening installs around the pipe and the outer diameter installs in the opening in the wall. The seal element is then mechanically compressed to seal the penetration.

 

The seal element is EDPM and the compression plates are 304L stainless steel or 316L stainless.

WA-GPW annular space seals waterproof multi pipe cluster requirements through a wall where close grouping of pipe or conduit is required.

Seal multiple pipe or conduit through the same wall opening.

Multi-Pipe and Conduit seals WA-GPW multi pipe through the same wall opening.

Compression annular space pipe seals, WA-GPW seal pipe/conduit penetrations in new walls.

The number of pipes or conduit that may be sealed through the same opening, is only limited by the opening size.

 

 


WA.GPWK split units: are used for sealing existing multiple pipe or conduit already through the wall. The split disc allows the unit to wrap around several pipes.

disk-seal-for-sealing-existing-pipe-through-a-single-coreconduit-seals-building-entry

They provide water, gas and smoke-tight sealing.

Disc seal materials are elastomer rubbers with stainless steel compression plates. The seals may be used with steel pipes, PVC, PE, Ductile and for sealing power cables.

Pressure sealing up to 36 psi (2.5 bars) (80 foot head).



Other applications:

snow-melt-pex-pipe-seals

Snow melt heating multi PEX pipe enter a building through a wall opening. WA-GPW discs provide a watertight seal for the pipe supply system. The number of zones in the melt system varies according to heat required.

For example (18) 5/8" PEX pipe can be sealed through a 12" core opening.

If the heating is an electrical power system, conduit or cord penetrations may also be seal with a multi port sealing system.through-wall-multi-pipe-sealing

Multi service watertight seals for conduit and pipes through one opening, in basement walls.

WA-GPSD annular space pipe seals waterproof large annular spaces between pipe and opening:

Large annular space conditions require annular space seals to waterproof the large opening. A double row of compression bolts are used for the compression plates.

WAGP-SD wide annular space seals provide watertight penetrations for pipes through wall structures.

Applications: for WAGP-SD seals

When a large pipe flange must pass through a wall with the pipe.
Over sized core drill openings.
Smaller diameter carrier pipe in a large casing.
Where large annular spaces exist for other reason.

WAGP-SD-split annular space seals are available for pipes that already exist.

  • Multi pipes through same opening with a large annular space.
  • Sealing for large annular spaces.

Compression plates 304L stainless or 316L stainless.
Seal materials: EDPM, NBR or Silicone elastomer.


Modular seal links "T" with silicone element rubber for high temperature.

For use with temperatures up to: (+230 ° C) / (+446 ° F).

Compression plates are stainless steel on "T" seal links.

WA-GPW disc silicone seals "T" seals for multi penetration high temperature applications.


Nylon compression plate WAGP-P composite disc seals are non metallic sealing units. Seal elements may be EDPM or NBR rubber seals. WA-GP-P seals are used for specific conditions where metallic seals cannot be used.

Applications:

- Pipe through wall seals
- Casing end seals

WAGP-P non-metallic disk compression seals are 14.5 psi seals. (33 ft water-head seals)

Double disc WA-GPP-DL models are 28 psi seals (64 ft water-head seals), that fit pipes from 3 inch up to 120 inch.

Non - Metallic compression seals may be used for non-centered pipes. Multi port openings for several pipes and conduit sizes through the same opening are available. No metal parts, non-conductive - total isolation.

When used as end seals the port opening axially accommodates the leg height used on the existing carrier pipe.


 

Advantages:

- Pressure sealing for pipes, Conduit, Cables through walls.
- Pressure sealing for end seals on a casing carrier pipe.
- Seals against liquids, gases and smoke.
- Reduces Vibration in the system..

A split version is used when long pulls are involved for conduit or pipe when longer runs are required after they enter a building.

Watertight sealing for multi pipe or conduit clusters.

EDPM, elastomer seals for water applications, NBR elastomer for hydrocarbon applications or Silicone elastomer for heat affected pipes. Sealing to 36 psi (80ft water head)


Seals are designed for all dimensions.
Provide watertight tight seals to 36 psi.
Prevent migration of liquids, gases and smoke.
Reduces noise.
Split version accommodate existing pipes, cables and conduit. Flexibility sealing.

Double Disc-Seals for pipes are used when higher pressure seals are required  up to 5bar - 72 psi. (160 foot water head)

The elastomer may be, silicone, NBR or EDPM.

The elastomer may be mix to meet field requirements: E.g. one elastomer disk silicone and the other NBR or other combination.
