Line sets consist of two semi-flexible copper pipes to connect the outdoor air conditioner or heat pump to the indoor evaporator coil. The smaller pipe measures 3/8" and is called the liquid line (LL). The larger pipe measures 5/8" and referred to as the suction line (SL) and both pipes are encased with thick 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.
