Forsheda 605 Sewer-Lock™, integrated sealing systems for sewer ans stormwater plastic pipes

System Description

The Forsheda 605 Sewer-Lock™ integrated system uses the mandrel together with the seal as a tool to form the pipe socket during the manufacturing process. The seal becomes part of the socket forming tool used to shape its own seal groove reducing irregularities and tolerances in the socket.

Seal design & function

The Forsheda 605 Sewer-Lock™ is a composite seal consisting of:

  • A flexible rubber element to seal effectively against spigot and socket

  • A polypropylene reinforcement element, bonded to the rubber, which holds the seal firmly in place

Seal Performance

The F-605 Sewer-Lock™ seal meets or exceeds current European and ISO standards for wastewater lines both for indoor and underground.

Furthermore, the seal design gives low assembly forces making pipe jointing easier.



The PIP-Lock seal is made from two materials. For dimensions 6in to 10in the sealing element is TPV and the plastic retaining element is polypropylene. 

The TPV material meets the American standard ASTM F-477. 

Detailed material specification is available on request.

Step 1

The spigot and socket of the pipe should be checked for damage prior to jointing. 

The pipe spigot should be chamfered with an angle of 15°, taking care to remove all burrs. 

Both spigot and socket including the sealing ring should be free from dirt and other foreign matter. 

Lubricant should be applied evenly to the spigot end of the pipe.

Step 2

Immediately after lubrication, the spigot should be brought into contact with the socket.

Both spigot and socket should correctly aligned and then slide the spigot into the socket, thus compressing the seal until the joint is fully made.
