Aopin Red Copper Refrigeration Tubing ID 4mm / 4/25" x OD 5mm / 1/5" Hollow Copper Tubing - 2m / 6.56 Ft / 79 in Length for Refrigerator Capillary Tubing, Cooling Systems

• ✔️Size: Inner Diameter: 4mm / 4/25", Outer Diameter : 5mm / 1/5", Length: 2m / 6.56 Ft / 79 In.
• ✔️Application Range: Due to the good plasticity and ductility of red copper pipes, red copper pipes are often used in refrigerator capillary tubes, pump lubrication systems, oil pressure systems, instrument pressure measurement, cooling systems, refrigerator / freezer / air conditioning heat conversion and other fields. At the same time, it can also be made into handicrafts, car models, mural decorations, frames, gardening products, etc. It is deeply loved by DIY enthusiasts.
• ✔️Material: Use safe and high quality red copper (copper content up to about 99.9%), good thermal conductivity, great electrical conductivity, airtightness and high strength. Because of the strong and corrosion resistant characteristics of red copper, it becomes the tap water of the house. The first choice for installation of piping, heating and cooling piping.
• ✔️Performance: Red copper is cut with professional cutting tools, the cutting surface is free of impurities, and both ends are equipped with dust caps to keep the copper tube clean, smooth surface, no joints, excellent ductility and pressure resistance. Light and convenient for replacement and maintenance. Easy to install.
• ✔️Coil red copper tubing is soft, can be bent and deformed, and can often be made into elbows and joints. Red Copper pipes can be perfectly capable of bending at any angle. When used as a pipe, there will be no problems such as yellowing of tap water and small water flow that occur with galvanized steel pipes.

Cooling capillary tube for air conditioner / refrigerator / freezer Our red copper pipes have good electrical and thermal conductivity, excellent cutting performance, excellent ductility, and excellent sealing properties. They are easy to heat and cold press, and have uniform color. They can be used for welding, punching or secondary processing. Red copper is cut with professional cutting tools, the cutting surface is free of impurities, and both ends are equipped with dust caps to keep the copper tube clean, smooth surface. Used to make handicrafts Red copper has bright color, smooth surface, high reliability, easy to connect to other parts, environmentally friendly materials, and can be recycled and reused. Note: The artwork needs to be polished with sandpaper first, otherwise the surface will rust and affect the appearance. When red copper pipes need to be welded, the welding position should be polished before welding.
