Copper
This insulated copper tube consists of twin seamless annealed copper with PE/NBR insulation. It used as connecting lines in split air conditioners (9000 BTU, 12000 BTU, 18000 BTU, 24000BTU, 48000BTU). This product is carefully designed to ensure best performance, easy installation and extended lifetime.
Insulation
The insulation of this product is available mainly in PE (Polyethylene) material*(1),It is used to limit transfer of energy from split air conditioner lines to the atmosphere in order to maintain proper sub-cooling values on the system. This insulation is nontoxic and it protects against chemical agents and UV rays. The two insulation tubes are lightly linked to allow easy separation while installing without altering its inner layers. *(1) Insulation in NBR available upon request.
