Product Description
The MRCOOL® MC16-1412 Mini Split Line Set Kit is a 16-foot flared copper refrigerant line set engineered specifically for 9,000, 12,000 and 18,000 BTU ductless mini split systems. Properly sized line sets are essential for maintaining correct refrigerant flow, compressor longevity, and overall system efficiency—and this OEM MRCOOL line set is built to those exact standards.
Constructed from high-quality refrigeration-grade copper, the MC16-1412 offers excellent thermal transfer, corrosion resistance, and long-term durability. The factory-flared ends allow for secure, leak-resistant connections, reducing installation time while ensuring proper sealing when paired with compatible MRCOOL and industry-standard mini split equipment.
With a 1/4" liquid line and a 1/2" suction line, this line set is perfectly matched for mid-capacity systems that require greater refrigerant volume than smaller 9K, 12K and 18K units. The 16-foot length is ideal for standard residential installs where indoor and outdoor components are located close together—minimizing excess tubing, pressure drop, and refrigerant imbalance.
Whether you’re installing a new MRCOOL mini split or replacing an existing line set, the MC16-1412 delivers OEM-level reliability and performance you can trust.

When installing line sets
When installing your MRCOOL system, handle refrigerant lines carefully to ensure optimal performance and prevent damage.
Prepare Components: Ensure all necessary components, including the line set, outdoor condenser unit, and indoor air handler, are ready for installation.
Bending the Copper Lines: Maintain a minimum 4-inch bend radius and use smooth curves instead of sharp angles to protect the lines and ensure proper refrigerant flow.
Avoid Repeated Bending: Bending copper lines more than three times can harden and weaken them, increasing the risk of breakage. Handle with care and minimize adjustments.
Connect Flared Ends: Attach the 1/4" and 3/8" flared ends of the line set to the corresponding ports on the outdoor condenser unit and indoor air handler, ensuring a secure and leak-free connection.
Secure and Protect: Properly secure the line set along its path and protect it from potential damage, ensuring optimal performance and longevity.
Professional Charging: As the line set is not pre-charged, have a certified HVAC professional charge the system with the appropriate refrigerant to meet your specific requirements
For best results, use gradual bends and consult a licensed professional or our support team if needed. MRCOOL DIRECT 615-553-8118
