Mini-Split Line Set 50 Ft 3/8" x 1/4" with 1/2" Insulation Contractor Pack

The Mini-Split Line Set 50 Ft 3/8" x 1/4" with 1/2" Insulation Contractor Pack (LS-MS381450P) is a standard Mueller Streamline refrigerant line set packaged for contractor inventory and repeat ductless installations. This set includes a 50 ft 3/8" suction line with factory-applied 1/2" insulation and a 50 ft 1/4" liquid line supplied together as a matched pair. Both lines are factory flared on both ends with flare nuts included, allowing direct connection to ductless equipment. This configuration is most commonly used on single-zone systems requiring extended routing. For proper job fit, technicians must verify allowable run length, elevation change limits, and flare compatibility with equipment connections. Contractor-packaged line sets reduce prep time and support consistent installation quality (includes insulated suction line and liquid line, factory flared with flare nuts).
