Key Benefits of Pre-Insulated Copper Tubing

Simplifies Installation and Saves Labor

Factory insulation eliminates the need for on-site wrapping, saving installation time and reducing labor costs while ensuring consistent insulation quality.

Enhances HVAC System Efficiency

Improved thermal performance reduces energy loss, helping the HVAC unit operate more efficiently and potentially lowering energy consumption.

Protects Against Moisture & Structural Damage

Proper insulation minimizes surface condensation and prevents moisture issues that can lead to mold or structural deterioration.

Installation Tips for Best Results

Measure Your Line Run Before Installation

Measure the total distance between indoor and outdoor units to ensure the 82 ft length is appropriate and allows smooth routing without excessive bending.

Protect Insulation at Wall Penetrations

Use a wall pipe sleeve where the tubing passes through walls or structures to avoid insulation damage and maintain airtight sealing.

Support Tubing During Long Runs

Use line clamps or HVAC support brackets to secure long runs of tubing, reduce vibration, and prevent sagging that might stress insulation or copper tubing.
