25ft Mini Split Line Set with 1/4 and 3/8 in Copper Tubing & Triple-Layer Insulation – HVAC Connection Kit (White)

25FT Copper Tube: With a length of up to 25ft, 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” high-pressure tubes and 3/8” low-pressure tubes, compatible with 0-12000 BTU split air conditioners, specifically designed for mini-split air conditioning systems.

Thickened Pure Copper Tube: Utilizes high-quality copper tubes compliant with ASTM standards, meticulously controlling the wall thickness of both high-pressure and low-pressure tubes, providing excellent toughness and hardness, eliminating the frustration of thin copper tubes easily flattening with a single fold.

Three-layer Insulation Cotton: Wrapped tightly with three layers of insulation cotton, the copper tube sustains effective insulation while being waterproof and pressure-resistant, offering better protection for the internal copper tubes.
