Mueller Streamline LS-MS121430P Mini-split Line Set 30 Ft

Product Description

The MUELLER STREAMLINE LS-MS121430P is a contractor-packaged mini-split line set designed for ductless HVAC installations. The set includes a 30-foot suction line measuring 1/2 inch in diameter with factory-applied 1/2 inch insulation, paired with a 30-foot liquid line measuring 1/4 inch in diameter. Both lines are factory flared on each end with flare nuts included, reducing field labor and minimizing installation variability. This line set is assembled as a matched pair, supporting consistent inventory management for contractors running repeat ductless jobs. Licensed HVAC technicians handling residential and light commercial ductless systems will find this set well suited to high-volume installation workflows.

This line set is configured for single-zone ductless mini-split systems requiring 1/2 inch suction and 1/4 inch liquid line connections. The 30-foot run length accommodates typical wall-penetration and short-run installations between the indoor air handler and outdoor condensing unit. The contractor pack format is intended for shops and service companies that benefit from stocking pre-matched, pre-flared line sets to reduce staging time on the job site. Technicians should verify that the 30-foot run length, line diameters, and flare connection specifications match the OEM requirements of the specific mini-split equipment being installed before committing to a run.

Key Features

• Matched pair: 30-foot 1/2 inch suction line and 30-foot 1/4 inch liquid line bundled together
• Factory-applied 1/2 inch insulation on the suction line reduces field insulation labor
• Both lines factory flared on each end with flare nuts included
• Contractor pack format supports inventory efficiency for repeat ductless installations
• Copper construction suitable for refrigerant service in ductless mini-split systems

Compatibility

Designed as an OEM-style replacement and new-installation line set for single-zone ductless mini-split systems requiring 1/2 inch suction and 1/4 inch liquid line connections. Technicians must confirm equipment manufacturer run length limits and flare connection specifications before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with applicable mechanical codes and the equipment manufacturer instructions. Power down and isolate the mini-split system completely before connecting or disconnecting refrigerant lines. Verify that all factory flare connections are properly seated and torqued to the equipment manufacturer specification before pressurizing the system. Do not over-bend copper lines during routing, as kinking will restrict refrigerant flow and void the installation.
