What Is A Ductless Line Set Cover?

A line set is a copper pipe where the refrigerant passes from the outdoor compressor to the indoor unit’s evaporator in a continuous cycle. It is made of two lines, namely, a larger suction line and a smaller liquid line. The line set is installed outside of the outdoor and indoor units. Therefore, it is vulnerable to the elements, and this can result in the line set corroding easier and quicker than it normally would. For instance, UV rays can affect the line set insulation as time passes.

This is where a line set cover comes in handy. It protects the line set, drain tube, and cable from element exposure. They are made to be resistant to even the harshest of weather so that your split system continues to function at optimum form.

Ductless Line Set Cover Components

  • Coupling/socket – is what you use to connect two split line pipes in a straight run.
  • End socket – seals the line set cover to the compressor.
  • Horizontal elbow – used to avoid turns and obstacles, such as windows, on the walls.
  • Split line tube – used for concealing and protecting the line set, drain tube, and connecting wire.
  • Vertical elbow – this is utilized when it is required to make turns like going around corners during installment.
  • Wall cover – covers up all holes and gaps around the line set’s wall penetration.
