About This Product

The MRCOOL DIY Ductless Split System Line Set is specifically engineered for use with MRCOOL DIY ductless mini split systems. If one standard line set isn’t sufficient, two can be joined using a compatible DIY coupler to achieve the required length. Each line set includes a 3/4 in. UV-protective insulation sleeve, offering added defense against sun exposure, weathering, and potential damage from animals or rodents. Quick-connect valves simplify installation, eliminating multiple traditional setup steps.

Highlights

• Includes a 3/4 in. UV-protective insulation sleeve for added durability 

• Features screw-on quick-connect valves for fast, secure attachment
