Mini split line set 50 ft delivers a clean, insulated connection between indoor and outdoor units for efficient refrigerant flow and easier HVAC installs. This dual copper tubing set includes 1/4 in and 1/2 in O.D. pipes with triple-layer insulation to help reduce energy loss and protect lines from moisture. Built for mini split air conditioners and heat pump systems where flexibility, durability, and a tidy finish matter.

• Connect indoor/outdoor units with a 50 ft reach for longer-distance mini split and heat pump installs.


• Fits common systems by pairing 1/4 in (high-pressure) and 1/2 in (low-pressure) copper tubing.


• Resists kinks with thick-walled copper designed to hold shape during bending and routing.


• Protects lines with triple-layer insulation that helps block moisture and reduce heat transfer.


• Includes wrapping strips and 2 tie wraps to bundle, secure, and finish the run neatly.

Designed for quick-scan installers and DIY upgrades, this insulated copper line set helps streamline mini split AC and HVAC routing while keeping lines protected along the entire run.
