25ft Mini Split Line Set

This 25ft copper line set connects indoor and outdoor mini-split units. It includes 1/4in high-pressure and 3/8in low-pressure tubes rated for systems up to 12000 BTU. The tubing uses ASTM-compliant copper with controlled wall thickness for durability. Triple-layer insulation provides waterproof and pressure-resistant protection.

Installers needing standard flare connections

The set suits HVAC professionals and DIYers installing compatible mini-split air conditioners or heat pumps. It is not for systems requiring larger diameter piping or different flare angles. Buyers needing pre-flared ends or different insulation ratings should look elsewhere. The fixed 25ft length cannot be shortened without specialised tools.

Coiled tubing requires careful unrolling

Installation involves uncoiling the 23.22in diameter roll without kinking the 6.35mm and 9.53mm tubes. Flaring the cut ends demands a quality flaring tool and deburring step to prevent leaks. Over-tightening flare nuts on the thin-wall copper is a common error. Two wrapping strips are included for finishing the insulation joints.

Questions about this item

What indoor and outdoor units can the 1/4in and 3/8in lines connect?

The 1/4in high-pressure and 3/8in low-pressure copper tubes are designed for 0-12000 BTU mini-split air conditioners and heat-pump systems.

Can I reuse my existing flare nuts and wrapping tape with this 25ft line set?

The kit includes the 25ft copper tubing and two wrapping strips, so you can install it without reusing old flare nuts or insulation tape.

How do I confirm the 25ft copper tubing is installed correctly?

After flaring and torquing the ends, pressure-test the 1/4in and 3/8in lines, then run the mini-split to verify cooling or heating performance.
