2MM OD X 1MM ID X 7.5 METERRefrigeration tube outer dia is 2mm / 5/64', inner dia is 1mm / 3/64', total length is 24.5Ft/6m long HIGH REFRIGERATION EFFICIENCYGood heat dissipation and refrigeration capability,high strength at low temperature.Copper tubes are hollow,so has strong heat transfer capability.If you need refrigeration for refrigerators, freezers, air conditioners, this is a good choice COPPER MATERIALCopper refrigerator tube has the features of high temperature resistance, corrosion resistance, oxidation resistance, durability, long service life SOFT & SHAPE CHANGEABLEBecause refrigeration copper pipe can bend and deform, they can often be made into elbows and joints. Smooth bending allows copper tubes to bend at any angle WIDELY APPLICATIONRefrigerator Tubing is not only used for refrigerator, freezer and air conditioner as refrigeration tubing coil, but also used as a HVAC system pipe.
