WiSecure W801

Special seals for water and radon – permit axial movement

WiSecure® W801 is a special seal for water and radon for round pipe cast into concrete walls and floor. The unique profile design of the ring in combination with associated hose-clips provides effective sealing between pipe and concrete while at the same time permitting axial movement.



Unique design

WiSecure® W801 is designed to work smoothly at both high and low water pressure. W801 is also designed to allow axial movement of the cast-in pipe.


Suits all pipe materials

W801 can be used for all types of pipe material, including plastics, steel, cast iron, concrete, etc, and permits large axial movement of pipes with smooth sides. However, the special profile of the rubber ring still provides effective sealing between pipe and concrete.


The choice is yours

WiSecure® seals have been on the market since the eighties. WiSecure® solves your sealing problems, and we can guarantee that you will be satisfied.



WiSecure W801 wall conversion is intended as a water and radon barrier for casting of pipes into concrete walls and floors.


W801 sealing is adjustable after casting and can be fitted from inside or outside the concrete wall. The special profile of the rubber rings provides effective sealing between pipe and concrete.



A groove in the larger rubber ring is filled with grease in order to allow shaft movement in the seal while at the same time preventing water ingress past the seal at any scratch on the pipe. The pressure of the collar makes the seal expand while the pressure against the surrounding concrete increases and grease is pressed out from the grease groove.



WiSecure® W801 is manufactured in SBR rubber with a hardness of 40° ± 5° IRHD. The material meets the requirements of Swedish Standard SS 367611, German Standard DIN 4060, and other national standards for rubber sealing rings. The clamping collar and crimping tool are supplied as standard in hot-galvanised steel.
