Annular Space Seals

Watertight, Gas-tight - Multiple or Single building entry sealing.

WA-GP annular space disc seals provide waterproof seal solutions for pipes entering a building or manhole.

WA-GP seals only require three inch seating space. Ideal for small diameter pipes or larger pipes.

Split models create a watertight sea around existing pipes.

Large or small annular spaces can be sealed when standard openings are not made.

Silicon elastomer may be used when high temperature "T" seals are required.

Multi-pipe sealing through a single core or wall sleeve opening.

WA-GPW annular space seals waterproof multi pipes that pass through the same opening. Snow melt multi PEX pipe seals.

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 MP) (2.5 bar)

Applications:

Seal round manhole pipe penetrations. Low seating space requirements for large pipes. Low curvature feature for small pipe diameters.

Watertight connections for large diameter pipes through thin wall manholes.

Watertight connections through undersized core drills.

WA-GPSR annular space seals for pipe through casing. WA-GPSR disc seals fit all American and International sizing.

Pipes pass through the inner opening, the outer diameter fits the wall opening.

The seal element is then mechanically compressed with tightening nuts to seal the penetration.

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

Multi-Pipe and Conduit seals WA-GPW

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

Seal multiple pipe or conduit through the same wall opening.

Multi compression annular space pipe seals, WA-GPW seal pipe/conduit penetrations through wall sleeve openings.

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.

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).

Snow Melt heating - wall penetration sealing.

Snow melt heating multi PEX pipe enter a building. WA-GPW discs provide a watertight seal for the pipe heating 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 power cable penetrations may also be seal with a multi port sealing system.

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

Large annular space pipe seals - WA-GPSD waterproof pipe penetrations.

WAGP-SD wide annular space seals for pipes with large wall openings. Large annular space seals have a double row of compression bolts. The seal may be closed for new pipe goinh through openings or split when the pipe is already in place,

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.

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.

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..

Scope of delivery:

Material: Pressure plates - corrosion resistant stainless steel V2A (AISI 304L); (V4A (AISI 316L) on request). Rubber: EPDM: -30C - +100C, NBR: -20C - + 90C

Tightness:
- Water/Gas tight

WA-GPDL units have increased rubber surface areas for increased water head conditions.

The units can accommodate 72 psi sealing (160 foot water head)

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.
