Class O is a flexible, closed cell, elastomeric, nitrile rubber insulation. It is a highly efficient method of insulating hot and cold water services, chilled water lines, heating systems, air conditioning ductwork and refrigeration pipework for frost protection, energy conservation and condensation control. It is dust, fibre and CFC free with an ODP of zero which means an environmentally friendly product; outdoor applications require special paint finish for frost protection. Temperature range : -50 to 110°C. Thermal conductivity : ≤ 0.034 W/(m.K). Water vapour permeability : ≥10,000 μ. Euroclass - tubes : BL-s3,d0.
For metric copper tube use.
