Copper capillary tubes are small-diameter copper tubes with precise dimensions that are commonly used in various applications, especially in the field of refrigeration and air conditioning. Copper capillary tubes are vital components in refrigeration and air conditioning systems, where they help regulate the flow of refrigerant to achieve precise temperature control. Their small size, durability, and resistance to corrosion make them suitable for these critical applications, contributing to the efficient operation of cooling and refrigeration equipment. Available in different straight lengths.
