Forsheda 103 is an integrated sealing system that is cast into the socket during pipe or manhole manufacture. The system can also be used for concrete pipe connections to manholes.
The elastomeric sealing element is a combined lip and compression seal.
The cast in protective strip of cellular plastic forms part of the system together with the rubber sealing element. During manufacture, storage, transport and handling the protective strip remains in the pipe socket. It prevents sand, clay, ice or snow entering the sealing area. It is removed in the trench before the pipes are assembled.
The compression section absorbs tranverse shear load in the joint and prevents concrete to concrete contact.
The retaining elements or anchors are cast into the concrete during pipe manufacture and secure the seal in the correct position.
The slurry lip seals against the pallet preventing ingress during concrete compaction.
The Forsheda 103 meets all relevant European standards. Joint performance is dependent on dimensional accuracy and surface finish of the socket and spigot.

Inspect the pipes and ensure they are in good condition. The white protective strip in the socket helps to keep the sealing area free from dirt, mud and gravel.
Remove the protective strip by gripping the tape and pulling towards the centre of the pipe. Small parts of the strip can remain in the pipe without affecting the
Ensure the spigot and socket are clean. Apply lubricant to the spigot. This should be spread evenly over the entire surface paying special attention to the front radius of the spigot.
Centre the spigot into the socket and push the pipes together. The socket design and wedge shaped seal provide a funnel action and help centre the pipes.
