What Is A Ductless Line Set Cover?

The line set is the copper tubing that carries the refrigerant from the outdoor compressor to the evaporator in the indoor air handler and vise versa. It has two lines: one smaller liquid line and a larger suction line. Unfortunately, line sets can be exposed to the elements and can cause them to corrode quicker and easier than they usually would.

A line set cover protects the line sets, the drain tubing, and the cable from exposure of the elements. These include UV rays that can break down the insulation of your line sets as time passes. They are designed to be weather-resistant so that your system can continue operating in tiptop shape even through the harshest of weather.

Parts Of A Line Set Cover For A Ductless Mini-Split

A line set cover is comprised of different parts that work together to ensure the correct installation. These are:

  • Split line tube – this hides and protects the line set, drain piping, and connecting wire from the elements.
  • End socket – this is used to seal the line set cover to the condenser.
  • Vertical elbow – it is used when there is a need to make turns such as go around corners or go through soffits during the ductless installation.
  • Horizontal elbow – this is used to make turns on the walls. It is put to use when there are obstacles, such as windows that need to be avoided.
  • Coupling/socket – this is for when you need to connect two split line tubes in a straight run.
  • Wall cover – it seals any gaps and holes around the wall penetration of the line set.

Rest assured that line set covers are for residential and commercial use. Therefore, you don’t have to worry as your home or office will look professional and clean at all times.

Line set covers are built to ensure that they follow the energy code requirements. They are equipped with a protective peel-off film so that it stays clean and is easy to clean as well.


There are also line set covers that can accommodate multiple line sets, which is essential when you have a multi-zone configuration in your home. Some even have quick snap covers to make sure that it won’t pop off.

Most importantly, line set covers are built to be durable with thick-walled construction. They undergo a process to ensure that they can stand against ultraviolet rays and protect the line set like they are supposed to. They also come with no-rust screws and a glossy finish, ensuring it can last under the elements for a long time.

Mitsubishi Line-Hide

Mitsubishi has created the Line-Hide system that is designed to conceal and protect the copper line set and control the wiring needed for the mini-split to operate correctly. UV rays and other elements hasten the breakdown of the insulation used for line sets. The line-hide acts as a barrier around the line set, making sure that it is not exposed to these harmful elements.

Line-Hide is made using superior quality PVC with UV inhibitors, making it perfect for outdoor use in all weather conditions. Line-Hide can also be painted on with most kinds of house paints so you can match it with your exterior décor. They can also be used indoors as it meets the UL94v-0 for interior applications.

Line-Hide comes in several sizes so that you have one that will fit into each cover diameter. Line-Hide is also easy to install as it comes with a modular design and snap-on parts. Screws are also included when they are needed in the installation. Use them anywhere you need to hide any cables, pipes, or wires.
