Isolated copper tubes
INSULATED COPPER TUBES FOR AIR CONDITIONERS AND COOLING SYSTEMS
Copper tubes (designed for use with R22, R407C, R410A refrigerants) are coated with polythene insulation, which is externally coated with polythene wrap. It protects insulation from mechanic damage, water steam, sun influence, etc.
