50 ft Copper Line Set

This 50 foot copper roll provides both liquid and suction lines for air conditioning installations. It is sized for 3/8 inch liquid and 5/8 inch suction outer diameters with half inch insulation thickness. The set arrives new and ready for professional HVAC technicians or experienced installers.

Simple Unroll and Braze

The copper tubing unrolls for straightforward measuring and cutting to fit the job site. Installers must braze joints correctly and pull a proper vacuum to avoid leaks or moisture contamination. No special tools beyond standard HVAC brazing equipment are required for the copper itself.

Stable Thermal Transfer

Half inch insulation helps maintain consistent refrigerant temperatures during extended cooling cycles. Copper construction resists corrosion and handles normal system pressures without degrading. The line set delivers reliable performance for the duration of the air conditioning season.
