What Is a Flared Line Set?

A flared line set consists of two copper refrigerant lines:

• Liquid Line (1/4") – Carries refrigerant to the indoor unit
• Suction Line (5/8") – Returns refrigerant to the outdoor condenser

The pre-flared ends allow for a secure connection to both the indoor air handler and outdoor unit without additional fabrication.

Why Choose a Pre-Flared Line Set?

• Saves time on installation
• Eliminates need for flaring tools
• Reduces installation errors
• Ensures consistent, professional-quality connections

Ideal For:

• DIY mini split installations
• MRCOOL system replacements
• HVAC contractors and installers
• System upgrades or line set replacements

⚠️ Compatibility Note

Always verify your system’s required line size before ordering. This line set is designed for systems that use 1/4" liquid and 5/8" suction lines, typically found in 24k–36k BTU mini split systems.
