System description
Forsheda 160 is a one-piece integrated seal that is cast into the socket during manhole manufacture. It is specifically designed for use with the spigot design according to DIN V 4034-1.
Seal design & function
- Sealing part, made of soft rubber, (40 IRHD) is a combined lip and compression seal. The soft rubber has excellent flexibility to take up irregularities in the spigot surface.
- Retaining sections are cast into the concrete during pipe manufacture and secure the seal in the correct position.
- Slurry lips seal against the base ring (pallet) pre venting concrete ingress during manhole manufacture. The lips are made of soft 40 IRHD rubber which gives an excellent seal between seal and base ring.

Forsheda 160 meets or exceeds the requirements of all current relevant European standards including the FBS demands.

Video Joint Assembly
Step 1
Apply lubricant to the spigot of the manhole. This should be spread evenly over the entire surface paying special attention to the top radius. Lubrication may also be applied to the seal to further assist jointing.
Step 2
Centre the socket over the spigot and lower the upper manhole element to complete the joint. Light weight elements may require an additional vertical force to fully close the joint.
