25 ft Mini-Split Line Set with Dual Copper Pipes

The VEVOR JSY-SS-SKU10 is a 25 ft line set that includes 1/4 in high-pressure and 1/2 in low-pressure copper tubes. It is designed for 12000 to 18000 BTU mini-split air conditioning or heat-pump systems. The set comes with a 27 ft connection cable, 9.8 ft drainage pipe and mounting accessories.

HVAC installers and DIY owners fitting standard

This kit suits technicians and homeowners installing or replacing a typical single-zone mini-split within the stated capacity range. It will not suit multi-zone systems requiring additional line sets, VRF installations, or units needing larger-diameter piping. Buyers needing longer runs or different pipe sizes should look elsewhere.

Pre-insulated copper ready for flare connections

The copper tubes meet ASTM wall-thickness specifications and are wrapped in three-layer insulation for thermal performance and moisture protection. A wall sleeve and sealant putty are included for penetration sealing. The installer must supply flare nuts, a flaring tool, torque wrench and any required electrical disconnect or mounting brackets.

Questions about this item

What indoor and outdoor units will the 1/4 in and 1/2 in copper pipes connect to?

The line set is designed for 12000-18000 BTU mini-split air conditioners or heat pumps that use 1/4 in high-pressure and 1/2 in low-pressure flare connections.

Will the 25 ft copper tubes and 27 ft connection cable reach my existing outdoor unit if it is mounted farther away?

The 25 ft copper length and 27 ft cable allow placement up to that distance; measure your actual run to confirm the slack is sufficient before cutting or flaring.

How can I verify the three-layer insulation is sealed and the flare joints hold pressure after installation?

After flaring and tightening the joints, run the system in cooling mode and check that suction and discharge pressures match the unit specifications while feeling that the insulation surface stays dry and at ambient temperature.
