50 ft. Copper Tube: With a length of up to 50 ft. the copper tube can easily connect indoor and outdoor units even over long distances without difficulty. High and Low Pressure Dual Pipes: Includes 1/4 in. high-pressure tubes and 3/8 in. low-pressure tubes, compatible with 0-12000 BTU split air conditioners, specifically designed for mini-split air conditioning systems.
