Wostore 50ft Split Line Set - 1/4 & 1/2 Inch Copper Pipe, Insulated PE

The Wostore 50ft Mini Split Line Set delivers reliable performance for ductless HVAC systems. Featuring pure copper tubing in 1/4" and 1/2" sizes, the set meets ASTM B743 standards for high and low pressure lines, ensuring leak-free operation. A thickened fire-retardant insulation layer wraps each tube, providing resistance to high temperature and pressure while quickly extinguishing flames. The embossed polyethylene film on the insulation adds abrasion resistance, blocks moisture, and reduces friction and noise during installation. Compatible with all major manufacturers-including Mitsubishi, LG, Fujitsu, and Daikin-this line set fits a wide range of air conditioner, refrigeration, and heating equipment. Easy to install with included nuts, the Wostore line set offers a durable, safe, and efficient solution for both new installations and system upgrades, giving homeowners and technicians confidence in long-lasting performance.
