MRCOOL Line Sets for Easy Installation and Reliable Performance
MRCOOL line sets are refrigerant connection solutions that include pre-charged No-Vac line sets, flared line sets, R-454B line sets, and LineGuard covers. Available in multiple configurations, they work with compatible mini split and geothermal HVAC systems. Options are available in 15, 25, 35, and 50 ft lengths, with tubing sizes such as 1/4" x 3/8", 1/4" x 1/2", and 3/8" x 5/8" for compatible mini split systems.
Over time, refrigerant lines may require replacement due to damaged components, installation changes, or HVAC system upgrades. Choosing the right line set helps maintain reliable refrigerant connections and supports easier installation. A MRCOOL No-Vac line set can simplify connections for compatible systems, while a MRCOOL precharged line set provides a convenient option for applicable installations. Protective LineGuard covers also help keep exterior refrigerant lines organized and protected.
At PartsHnC, we offer MRCOOL mini split line sets in multiple lengths and tubing sizes for compatible HVAC systems. Choose a flexible mini split line set based on your system requirements and installation needs.
