Armaflex selfseal is a closed cell, elastomeric, nitrile rubber insulation, with in-built anti-microbial protection, fully slit along each length with double sided adhesive tape pre-applied to each open slit. Built in vapour barrier prevents condensation. It is a highly efficient method of insulating hot and cold water services, chilled water lines, heating systems; outdoor applications require special paint finish for frost protection.
