MRCOOL 25 Ft. Pre-Charged Quick Connect Line Set, 3/8" x 5/8", for DIY 5th Gen EasyPro 24K Mini Split System

The MRCOOL DIY® 5th Gen 25 ft Pre‑Charged Quick Connect Line Set (3/8″ x 5/8″) is a ready‑to‑install refrigerant line designed for use with MRCOOL DIY 5th Gen EasyPro 24K mini‑split HVAC systems. This line set arrives factory pre‑charged with R‑454B refrigerant, which eliminates the need for vacuuming or refrigerant charging during installation. With MRCOOL’s Quick Connect® fittings, users can make secure, leak‑resistant connections without specialized HVAC tools — simplifying the installation process for both DIYers and professional installers.

The line set is sized with a 3/8″ liquid line and a 5/8″ suction line, tailored to the requirements of the 24K indoor unit. Its 25 ft length provides flexibility for standard installations where the indoor and outdoor units are placed at moderate distances. This makes it suitable for typical residential layouts, helping ensure proper refrigerant flow and system performance.

Constructed with durable materials and weather‑resistant insulation, the line set is built to withstand outdoor exposure and protect internal refrigerant lines. Its design supports reliable performance throughout the year, helping maintain efficient heating and cooling operation for your MRCOOL mini‑split setup.

Ideal for homeowners or installers working with DIY 5th Gen EasyPro systems, the MRCOOL pre‑charged Quick Connect line set delivers a practical and user‑friendly solution for connecting mini‑split components — reducing installation complexity without compromising on quality or performance.
