Description
Line sets consist of two 50 feet commercial grade copper refrigeration pipes to connect the outdoor air conditioner or heat pump to the indoor evaporator coil. Designed with a rugged exterior to allow for easy installation, this line set can be easily pulled. The 1/4" smaller pipe is called the liquid line (LL). The 1/2" larger pipe is referred to as the suction line (SL), & both pipes are encased with 1/2" thick low-density polyethylene foam 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 & Materials (ASTM) Standard Specification B280. This line set includes 53 feet of 14-4 AWG 600V wire for electrically connecting the indoor evaporator to the outdoor unit.
