Copper tubing connects the outdoor condenser to the indoor coil and allows the refrigerant to travel back and forth from these units. It is best to replace your copper line set when installing a new system, especially if you switch refrigerants. This will ensure there are no leaks or contaminates that will affect the efficient operation and longevity of the new system.
Features
One roll each of 1/4″ and 5/8″ tubing
Both lines are fully insulated (1/2″ thickness)
Flared fittings for quick installation
Available in 15 foot, 30 foot or 50 foot rolls of copper tubing
Does not come pre-charged with refrigerant
Coiled for convenient handling and storage
*Please check with your HVAC contractor to make sure you purchase the correct size copper for your system and application. Copper size requirements can vary based on the system and length of your copper line set. Condenser specification sheets can assist with the selection of copper tubing.
