50ft Mini Split Line Set

This 50ft line set connects indoor and outdoor mini-split units using 1/4in high-pressure and 1/2in low-pressure copper tubing. The pipes meet ASTM standards for wall thickness and are wrapped in three-layer insulation cotton for waterproof and pressure-resistant protection. Wrapping strips and a user manual are included for installation.

Ideal for 12000-18000 BTU systems

Installers fitting 12000-18000 BTU mini-split air conditioners or heat pumps will find the dual-pipe diameters match common specifications. The 50ft length covers extended runs between units. Builders needing different pipe diameters, shorter lengths, or compatibility outside the 12000-18000 BTU range should look at other kits.

1/4in and 1/2in O.D. copper pipes

The set provides one 1/4in outer-diameter high-pressure tube and one 1/2in outer-diameter low-pressure tube, both made from thickened pure copper. This specific pair of diameters determines whether the line set matches the refrigerant ports on the target mini-split equipment.

Questions about this item

Should I pick the 1/4" high-pressure line or the 1/2" low-pressure line for my install?

Both are included; the 1/4" line handles high-pressure refrigerant and the 1/2" line handles low-pressure suction, so you use them together.

What does the 50 ft length mean once the coil is unrolled on site?

You get 15240 mm of continuous copper tubing to span the distance between indoor and outdoor units without joints.

How does the 1/2" outer diameter low-pressure pipe limit the system capacity in practice?

The 12.7 mm tube is sized for 12000–18000 BTU mini-split units, matching typical residential heat-pump capacities.
