Rather than being limited by shorter line sets that restrict placement options, the MRCOOL MC50-1412 provides the reach needed for more flexible mini split installations. It is well-suited for projects where indoor and outdoor units must be positioned farther apart, such as larger homes, additions, or workspace areas.
The MRCOOL 50FT 1/4" x 1/2" Flared Line Set is engineered for 12K and 18K BTU mini split systems that require a 1/4" liquid line and a 1/2" suction line. It works with MRCOOL Olympus Series and Advantage Series 12K and 18K systems, along with other mini split systems matching these sizing requirements. Since this is a non-DIY line set, proper installation, evacuation, and charging must be completed by a licensed HVAC professional.
Built with high-quality copper tubing, the MRCOOL 50FT 12K & 18K Mini Split Line Set supports consistent system performance across longer distances. The factory-flared ends are designed to create secure connections, helping reduce the risk of leaks when installed to manufacturer specifications. Its extended length also helps minimize the need for additional joints or extensions during installation.
Overall, this line set delivers a dependable and practical solution for extended-run mini split applications where proper sizing and connection reliability are essential.
