7620mm Mini Split Line Set, 6.4 & 12.7mm OD Copper Pipe and Triple Layer Insulation, for Mini Split Air Conditioning Refrigerant or Heat Pump Equipment & HVAC with Wrapping Strips.

25FT Copper Pipe: With a length of up to 25 feet, the copper pipe can easily connect indoor and outdoor units even over long distances without difficulty.
Dual high and low pressure pipes: Includes 1/4" high pressure pipe and 1/2" low pressure pipe, compatible with 12000-18000 BTU split air conditioners, specially designed for mini-split air conditioner systems.
Thickened pure copper tube: Using high-quality copper tubes that comply with ASTM standards, carefully controlling the wall thickness of both high-pressure and low-pressure tubes, providing excellent toughness and hardness, eliminating the frustration of thin copper tubes that are easily flattened with a single bend.
Three-layer insulation cotton: tightly wrapped with three layers of insulation cotton, the copper pipe maintains effective insulation while being waterproof and pressure-resistant, providing better protection for the internal copper pipes.
