15240mm Mini Split Line Set, 9.5 & 15.9mm OD Copper Pipe and Triple Layer Insulation, for Mini Split Air Conditioning Refrigerant or Heat Pump Equipment & HVAC with Wrapping Strips.

50FT Copper Pipe: With a length of up to 50 feet, the copper pipe can easily connect indoor and outdoor units even over long distances without difficulty.
Dual high and low pressure pipes: Includes 3/8" high pressure pipe and 5/8" low pressure pipe, compatible with 18000-26000 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 fold.
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.
