F-154 is a pre-lubricated sliding seal that is stretched onto the spigot of the manhole. Additional lubricant is not required for joint assembly. The joint design is standard in many countries. Lubricant has been applied between the sliding skin and the body of the seal. This design permits in-stallation with very low force, as there is no friction between rubber and concrete. The special design of the joint and seal make the system easy to centre during jointing.
The F-154 seal meets all relevant current European standards. Joint performance is dependent on dimensional accuracy and surface finish of socket and spigot.

On each seal, profile thickness, outer diameter, recommended pipe measurement and production period are given. The corresponding data are also on the packaging.
Subject to change for technical reasons
Stretch the seal onto the spigot and position against the shoulder.
Equalize the stress in the seal by lifting and releasing at a few points. The seal must sit evenly against the spigot shoulder all around the manhole. Lubrication of the socket or spigot is not required.
Centre the joint and assemble. The position of the seal in the final mahole joint is shown in the figure.
If re-joining is required ensure the sliding skin is drawn back to the position as shown in Figure 1.
