MRCOOL® 16FT 1/4" x 3/8" Flared Line Set Kit for (9K-12k) Olympus and Advantage Mini Split, MC16-1438
Product Description
The MRCOOL® MC16-1438 Mini Split Line Set Kit is a 16-foot flared copper refrigerant line set engineered specifically for 9,000 and 12,000 BTU ductless mini split systems. Proper line sizing is critical for system efficiency, refrigerant balance, and long-term compressor reliability—this OEM MRCOOL line set is built to meet those requirements precisely.
Manufactured from high-quality refrigeration-grade copper, the MC16-1438 delivers excellent thermal transfer, corrosion resistance, and flexibility for easier routing during installation. The factory-flared ends ensure a secure, leak-resistant connection when paired with compatible MRCOOL and industry-standard mini split equipment.
With a 1/4" liquid line and 3/8" suction line, this line set is perfectly matched to smaller-capacity systems, helping maintain optimal operating pressures and performance. The 16-foot length is ideal for standard residential installations where indoor and outdoor units are located nearby—reducing excess tubing, pressure drop, and installation time.
Whether you’re installing a new MRCOOL mini split or replacing an existing line set, the MC16-1438 delivers trusted OEM quality for dependable, long-term performance.

FREQUENTLY ASKED QUESTIONS
Q: What size mini split systems is this line set designed for?
A: This line set is designed for 9,000 and 12,000 BTU mini split systems.
Q: Are the line ends factory flared?
A: Yes. Both copper lines come factory flared for proper sealing.
Q: Can this line set be shortened if needed?
A: Yes, but it must be cut and re-flared correctly by a qualified installer.
Q: Is this an OEM MRCOOL product?

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
