The MRCOOL DIY Quick Connect Line Set is designed to make installing your ductless mini split system simple, fast, and completely DIY-friendly. Compatible with MRCOOL DIY 5th Gen Single Zone, Multi-Zone, and Central Ducted systems, this line set connects the outdoor condenser to the indoor air handler with ease. It comes pre-charged with eco-friendly R-454B refrigerant and features Quick Connect fittings, eliminating the need for cutting, brazing, vacuuming, or charging—saving both time and installation costs.

Built for durability, the line set includes a 3/4-inch UV protective insulation sleeve that helps guard against sun damage, harsh weather, and wear from outdoor elements or animals. Its kink-resistant design makes it easy to bend and route during installation, ensuring flexibility without compromising performance. If additional length is needed, multiple line sets can be connected using a coupler, allowing extensions up to 75 feet for larger installations.

Available in 16 ft, 25 ft, 35 ft, and 50 ft options, these line sets are tailored to fit different installation needs. The 35 ft and 50 ft versions include an extended DIY Pro Cable for added convenience, while the 75 ft setup combines a 50 ft and 25 ft line set with a coupler kit. Different size options ensure compatibility with various air handlers, delivering efficient and reliable system performance for any setup.
