Bosch 1/4 in. x 1/2 in. x 15 ft. Universal Piping Assembly for Ductless Mini-Split

Insulated refrigerant line-set, communication cable and power wires run from the outdoor compressor to the indoor air handler so no electrical work is needed inside the building. The line set consist of 2 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). The tubing is easily connected by the pre-flared fittings eliminating the need to solder.
