  • 1/4" and 1/2" dual pipes suit 12000-18000 BTU mini-splits
  • ASTM-grade thickened copper resists flattening during installation

Line set for 12–18 k BTU mini splits

This 16 ft copper line set includes 1/4 in high-pressure and 1/2 in low-pressure tubes sized for 12000–18000 BTU mini-split air conditioners or heat pumps. It ships with an 18 ft connection cable, 9.8 ft drainage pipe, wall sleeve, sealant putty, wrapping strips and a decorative cover. The kit suits installers and DIY owners running a single-zone system between indoor and outdoor units.

Insulated copper resists flattening and moisture

Thick-walled copper tubes meet ASTM specifications and resist kinking or flattening during bending. Three layers of insulation cotton wrap each tube, providing thermal protection while remaining waterproof and pressure-resistant. The assembly weighs 3.3 kg and measures 540 × 540 × 50 mm overall, keeping the refrigerant circuit stable in normal heating or cooling operation.

Coiled kit fits tight wall penetrations

The pre-coiled set arrives in a 21.26 in diameter package that passes through standard wall sleeves without extra cutting. Included sealant putty and wrapping strips seal the penetration, while the decorative cover finishes the exterior neatly. No additional tubing, cable or insulation is required for a typical single-zone installation, freeasing the installer from sourcing separate components.

Questions about this item

How do I install the 1/4 in and 1/2 in copper tubes without flattening them?

Use a proper tube bender for the 6.35 mm and 12.7 mm pipes; the thickened pure copper walls resist kinking but sharp hand bends still flatten the tube, so support the wall while forming each radius.

What maintenance will the triple-layer insulation and drainage pipe need later?

Inspect the 9.8 ft drain line each season for algae blockages and check the three-layer wrap for tears or UV damage; replace any section that stays damp or shows cracked cotton.

At what length does pressure drop become the first limit on a 12000-18000 BTU mini-split?

The 16 ft copper run stays within typical design limits for 12000-18000 BTU units; pressure drop only becomes the limiting factor if you extend the line set beyond the supplied length.
