This 50 ft mini split line set includes insulated copper tubing with flared nuts, plus a complete accessory kit to help simplify mini-split HVAC or heat pump installations. The copper lines are made from 99.9% pure C12200 copper with thick walls to resist kinking and help reduce leak risk. The kit also includes extra-long 52 ft wiring, a drain line, wall sleeve, decorative cover, strapping tape, and sealant putty for a ready-to-install setup. Designed around a standard 3/8 in liquid line and 5/8 in suction line configuration, it is intended to fit 18,000–26,000 BTU mini-split systems.
