How to Install Self Seal Pipe Insulation
Installation is straightforward: cut the insulation to the required length, open the pre-slit along the length of the tube, place around the pipe and press the self-adhesive strip firmly closed. For bends and elbows, cut mitres at 45° and seal the joints with foil tape or contact adhesive for a neat finish.
