Modular Link Seals For Large Diameter Pipes - Annular seals
WA-LS-GKD modular links, seal pipe penetrations: Steel, Concrete, Cast iron, HDPE, PVC pipes and all pipe sizes.
Modular seal links create a positive seal both inwards and outwards to effective pressure sealing for pipes through concrete walls. Creating a watertight annulus.
Resists: up to 5 bar (72 psi) pressure, at temperatures from, (-40 F to + 176 F), -40 ° C to + 80 ° C.
316L stainless bolts and nuts are standard hardware. The seal is placed in the annular space between the interior diameter of the wall opening and the pipe.
By tightening the bolts, the elastomer is compressed and expands between the pressure plates. The expanding elements provide a watertight and gas tight seal.
New features include a bolt tight confirmation window that advises installers when optimum torque is set on the bolt.
No under tightened links that may cause leaks.
Nuts are embeded in the compression plates which is a new and effective no part lost feature.
See seal link sizing charts for pipe through core drill walls
Watertight solutions for Water treatment plant pipe systems, sewage storage tunnels, manhole hole connector pipes, under ground tunnels, foundation structures. No leaks.
Pipe seals for all American and International diameter pipes.
- Nuts are molded into the pressure plate, no lost parts at the job site.
- Optimum tightness confirmation at a glance.
Watertight solutions for pipe passage through concrete walls.
American and International Pipe Sizes
Large Pipe diameter series:
Optimized compression bolts - nuts are embedded in the pressure plates.
Tight up to 72 psi (5 bar) ( Lloyd register).
"Yellow window indicators" - "Safe" - "Watertight"
Seal elastomers may be EDPM or NBR, bolting hardware is 316L stainless steel.

Compression Disc - pipe seals WA-GP units watertight connection for pipe through concrete walls. Disc seals only require a very low seating area. Ideal for watertight pipe connections through manhole walls.
Compression disc seals for through wall conduit and pipes. Including a split versions, for pipes that are already in place.
Compression disc seal sizing is determined based on the number of pipes or conduit through the same opening. Hole size is the determining factor for the number of pipes that can be sealed using multiple disk compression seals.
Compression disc pipe sealing is used for multiple pipes through the same opening, large annular spaces, holes or core holes too small for other types of pipe seals, when higher pressure seals are required. Eccentric compression disk seals are used for pipes that are off center through a pipe sleeve or drill core.
PUDDLE FLANGES: WA-PF units provide Waterstop pipe sealing. They are cast in a wall around a pipe through a foundation wall, floor slabs, pools, Ice rink concrete slabs. The units prevent water infiltration along a pipe through the concrete.
EDPM puddle flanges provide waterstops when a continuous pipe runs through the wall.
