PREMANT district heating pipe
Shrink-on closure
Shrink-on closure/end cap
PREMANT shrink-on closures protect the PUR insulation on the front of the PREMANT district heating pipes against
splashing water in buildings and shafts. The shrink-on closure is not necessarily watertight in contact with water (floo-
ding). The shrink-on closure also stops gas escaping from the PUR insulation at the end of the pipe.
