25ft Mini Split Line Set for HVAC

This 25ft copper line set connects indoor and outdoor units of mini-split air conditioning or heat pump systems up to 12000 BTU. It includes 1/4in high-pressure and 3/8in low-pressure tubes built to ASTM specifications. The kit suits installers or DIY owners completing a new installation or replacing existing refrigerant lines.

Installation uses pre-flared copper

The pipes arrive pre-flared and wrapped in three layers of insulation cotton that resists water and pressure. Copper meeting ASTM standards resists flattening during bending. Common issues include kinking the tube if bent too tightly, damaging the flare faces when tightening, or leaving the insulation compressed at wall penetrations.

Verify your system matches 1/4in and 3/8in O.D.

Confirm the indoor and outdoor units accept 6.35mm and 9.53mm outer-diameter flared connections before ordering. The 27ft connection cable, 9.8ft drain pipe, wall sleeve, sealant putty, wrapping strips and decorative cover are included. Ensure the 25ft run length covers your specific routing distance.

Which line-set length matches a 12000 BTU mini-split installation?
