Goodman ls141212100dmsf Refrigerant Line Set 100 Ft

Product Description

The GOODMAN ls141212100dmsf is a copper refrigerant line set engineered for ductless and mini-split system installations. It consists of two insulated copper lines: a 1/4-inch plain liquid line and a 1/2-inch plain suction line, both running 100 feet in length. Each line is wrapped with 1/2-inch insulation to minimize heat gain and condensation. Ends are factory-flared for a leak-resistant mechanical connection. Licensed HVAC technicians use this line set to connect an outdoor condensing unit to an indoor air handler in split-system configurations where long runs are required.

This line set is suited for residential and light-commercial ductless mini-split installations where the indoor and outdoor units are separated by significant distance. The 100-foot length accommodates installations with longer line runs, such as multi-story buildings or units mounted on opposite sides of a structure. The flared end connections are compatible with standard flare fittings used on most mini-split systems. Both lines ship insulated and ready for installation, reducing field labor on longer runs.

Key Features

• Copper construction for durability and refrigerant compatibility
• 1/4-inch plain liquid line and 1/2-inch plain suction line in a single set
• 100-foot length for long-run mini-split installations
• 1/2-inch insulation on both lines to limit heat transfer and condensation
• Factory-flared ends for a reliable mechanical connection without field flaring
• Ductless and mini-split system type for targeted application fitment

Compatibility

Designed as an OEM-style refrigerant line set for ductless and mini-split split-system installations requiring a 1/4-inch liquid line and 1/2-inch suction line with flared connections.

Installation Notes

Installation should be performed by a licensed HVAC technician holding an EPA Section 608 certification. De-energize and recover any refrigerant from the system before disconnecting or connecting line sets. Inspect flare connections for damage before torquing fittings to equipment manufacturer specifications. Protect insulation from UV exposure and mechanical damage during and after installation per local mechanical code requirements.
