Mini-Split Line Set 50 Ft 5/8" x 3/8" with 1/2" Insulation LS-MS583850

The Mini-Split Line Set 50 Ft 5/8" x 3/8" with 1/2" Insulation (LS-MS583850) is a Mueller Streamline refrigerant line set for ductless installations requiring larger line sizing and extended routing. This set includes a 50 ft 5/8" suction line with factory-applied 1/2" insulation and a 50 ft 3/8" liquid line supplied together as a matched pair. The copper lines are factory flared on both ends with flare nuts included, enabling direct connection to compatible equipment. This configuration is most commonly paired with higher-capacity single-zone systems, with limited multi-zone use only where approved by the equipment manufacturer. For proper job fit, technicians must verify required line sizes, confirm allowable total length and elevation, and ensure proper flare seating and torque (includes insulated suction line and liquid line, factory flared with flare nuts).
