MRCOOL® 25 FT Flared Line Set Kit – 1/4" x 1/2" for 12K & 18K Mini Split Systems

MODEL: MC25-1412

The MRCOOL® 25 FT Flared Line Set Kit (MC25-1412) is designed for 12K and 18K MRCOOL® Ductless Mini Split Systems, providing a secure, professional-grade connection between the indoor and outdoor units.

Constructed from durable copper tubing with pre-flared fittings, this line set ensures easy installation and reliable performance. Its 25-foot length provides additional reach and flexibility, making it ideal for setups where indoor and outdoor units are farther apart.

Unlike No-Vac® pre-charged line sets, the MC-series uses traditional flared connections, making it perfect for HVAC professionals and installers who prefer more control over the installation process.
