Line-Hide Buying Guide

Mitsubishi's Line-Hide system of line set covers is the perfect product to protect your copper line sets from the elements. They're 100% paintable too, so you can preserve the architectural integrity of your home!

Presenting Mitsubishi's Line-Hide!

Often, you'll need to run a significant length of your line set outdoors before it penetrates through your wall. The Line-Hide system protects your line sets from exposure to the elements, including UV rays which can break down insulation over time. They are also designed to protect drain lines and wiring. As an added benefit, the Line-Hide system is paintable so you can match the color of your siding, preserving the décor of your home.

Common Questions

What is Line-Hide?

Line-Hide is a product from Mitsubishi Electric that is designed to conceal and protect your copper line set and control wiring required for a mini-split air conditioner.

Can UV rays really damage my line set?

The insulation used in line sets does break down over time. Direct exposure to sunlight and the elements hastens this breakdown.

How does Line-Hide help?

Line-Hide helps protect line sets because it forms a barrier around the line set and control wiring that prevents direct exposure to sunlight and elements. Line-Hide is made of high quality PVC with UV inhibitors for outdoor service in all weather conditions.

Can I paint Line-Hide?

Yes! Line-Hide can be painted with most house paints to match exterior décors.

How do you install Line-Hide?

Installation is a breeze with the modular design and snap-on components. Where screws are required, they are included with the products.

Can I use Line-Hide indoors?

Yes! Line-hide meetes UL94v-0 for interior applications. Use it anywhere you want to conceal cabling, piping, or wiring.
