【1/8" OD X 5/64" ID X 16 FT】Refrigeration tube outer dia is 3mm, inner dia is 2mm, total length is 16Ft/5m long 【HIGH REFRIGERATION EFFICIENCY】Good 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 MATERIAL】Copper refrigerator tube has the features of high temperature resistance, corrosion resistance, oxidation resistance, durability, long service life 【SOFT & SHAPE CHANGEABLE】Because 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 APPLICATION】Refrigerator Tubing is not only used for refrigerator, freezer and air conditioner as refrigeration tubing coil, but also used as a HVAC system pipe.
