Seal design & function
Trelleborg 104 Delta is a sliding seal that is stretched onto the spigot end of the pipe or manhole. Lubricant is applied to the socket prior to jointing.
Its design makes it easy to center during jointing, permits installation with very low force and it is standard in many countries.
Joint performance is dependent on dimensional accuracy and surface finish of socket and spigot.
It meets the requirement of all relevant current European standards.
