Copper Tubing for HVAC/R Applications
Designed for compatible air-conditioning, heat-pump, mini-split, and refrigeration installations requiring insulated copper tubing.
Factory-Applied Insulation
Each copper tube is covered with 1/2-inch insulation to help limit heat transfer and reduce condensation along the refrigerant line.
Made for Indoor and Outdoor Runs
The insulation is designed to resist ultraviolet exposure, tearing, moisture, and normal conditions found in HVAC installations.
Plain Ends for Field Preparation
Plain copper ends give installers the flexibility to prepare the tubing for the connection method required by the selected equipment.
Protected During Storage and Handling
Plastic end caps help keep dirt and debris out of the copper tubing before it is cut and connected.
Two Roll Lengths Available
Choose a 50-foot roll for shorter installations or a 164-foot roll when longer runs or multiple cuts are required.
