End caps are suitable for gable-end protection against water in order to avoid moisture penetration into the PUR-foam at the pipe ends, in buildings or constructions. Inside of manholes the end caps have to be secured against flooding with heating water. Additionally end caps will protect against diffusion of PUR-foam cell gas which will occur at the open pipe ends.

All end caps consist of a heat shrinking, molecular cross linked, modified and therefore nonweldable Polyolefin, and are coated by a special temperature resistant sealing adhesive at both ends. Resistant against weather conditions and chemical influence as well as UV-radiation and alkaline soil.
