Line sets consist of two semi-flexible copper pipes to connect the outdoor to the indoor evaporator coil. The smaller pipe is called the liquid line (LL). The larger pipe is referred to as the suction line (SL), and they both include insulation. The tubing is easily connected by the pre-flared fittings without the need to solder. They are manufactured in accordance with the American Society for Testing and Materials (ASTM) Standard Specification B280.
