Mini Split Line Set. We use high-quality copper tubes that comply with ASTM standards, offering excellent toughness and hardness. The three-layer insulation cotton provides effective insulation, specifically designed for mini-split air conditioning systems. Utilizing pure copper pipes, our products offer flexibility, allowing bending and straightening without breaking. They resist pulling and bending, with sufficient length to connect indoor and outdoor units. Even when encountering corners that require bending, piping is easily managed. The refrigeration copper tube contains high-pressure and low-pressure tubes, designed specifically for mini-split air conditioning systems used in homes, offices, malls, restaurants, and similar spaces. We strictly control the materials used, rejecting inferior ones. We use high-hardness thickened brass nuts, fluoroelastomer-coated smooth flare mouths, and protective covers to prevent dust from entering the copper tubes. To better protect the internal copper tubes, unlike ordinary double-layer insulation materials, three-layer insulation materials are employed for superior insulation performance. The embossed surface treatment enhances durability, showcasing undeniable strength.

• 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.
• 4-Step Quick Installation: Equipped with 2 tie wraps, installation is extremely simple, requiring only 4 steps to complete, effortlessly connecting indoor and outdoor units.
