Product Overview: 50 ft Insulated Copper Pipe for HVACR

This 50 ft insulated copper pipe set is built for air conditioning and refrigeration line runs where stable refrigerant flow and insulation performance are required. The 3/8" and 7/8" copper pipe combination is commonly selected for larger ductless mini split, heat pump and HVAC systems.

The factory-applied insulation helps reduce heat transfer, minimize pipe sweating and protect the copper tubing from weather exposure. Final pipe size, line length and refrigerant charge should always follow the HVAC equipment manufacturer’s installation manual.
