Mini split line set 25 ft delivers reliable refrigerant flow with triple-layer insulation to reduce heat loss and protect copper tubing from moisture. This dual copper pipe set (3/8 in + 5/8 in O.D.) is built for mini split air conditioner and heat pump HVAC installations where flexibility, kink resistance, and clean routing matter. Thickened copper helps prevent flattening during bends, while the pre-insulated wrap supports faster, neater installs between indoor and outdoor units.

Built for installers and DIY replacements, this insulated copper line set helps reduce common headaches like soft tubing that crimps during bends, exposed lines that sweat, and messy bundles that are hard to secure. Use it for mini split refrigerant applications and HVAC heat pump setups where consistent insulation and dependable copper quality are essential. Measure your required run and match the pipe diameters before installation. Grab yours today and get your system connected with a cleaner, more protected line run.
