Copper Line Set for Mini-Split Systems
This 35-foot copper line set connects the indoor and outdoor units of ductless mini-split air conditioning and refrigeration systems. It includes both the liquid and suction lines needed for a complete refrigerant circuit. Installers use it for new installations or line replacements where flare connections are required.
Practical Limits of Flare Connections
The 1/4-inch liquid line and 1/2-inch suction line both terminate in flared ends, so no brazing equipment is required on site. The 1/2-inch insulation thickness helps control condensation and thermal loss on the suction side. Flare fittings demand precise torque and clean sealing surfaces to prevent leaks under operating pressure.
35-Foot Length Determines Fit
The fixed 35-foot length is the single specification that decides whether this set suits the installation. Measure the exact routing path between the indoor and outdoor units before purchase; excess length cannot be removed without cutting and re-flaring, while a shortfall requires a different set.

Questions about this item
Should I pick the 35 ft set or a different length?
Choose the 35 ft length when the outdoor unit sits roughly that distance from the indoor head; excess coil adds pressure drop and insufficient length will not reach.
What does the 35 ft length mean once the lines are installed?
It gives a 35 ft run between the condenser and the evaporator, covering typical single-zone mini-split spacing with both liquid and suction lines pre-insulated.
Are the flared ends compatible with standard mini-split flare ports?
The liquid line has a 1/4 in. O.D. flare and the suction line a 1/2 in. O.D. flare, matching the common flare sizes used on residential mini-split and AC units.
