50 ft. Mini Split Line Set Copper Tubing Pipes and Black Triple-Layer Insulation for Air Conditioning

Pre-Insulated Copper Piping for Mini-Split Air Conditioners

Our pre-insulated copper line sets are designed to provide reliable and efficient connections between indoor and outdoor units in ductless mini-split air conditioning and heat pump systems. Manufactured from high-purity refrigeration-grade copper tubing compliant with ASTM B280 standards, these pipes ensure excellent durability, flexibility, and long-term performance.

Each line set features factory-applied closed-cell insulation that provides superior thermal protection, moisture resistance, and energy efficiency. The insulation also helps prevent condensation while maintaining optimal refrigerant temperature during system operation.

Built to meet Canadian HVAC industry requirements, our pre-insulated copper piping is compatible with modern refrigerants such as R410A, R454B and R32 and is suitable for residential and light commercial installations.

Available in multiple sizes and lengths, these line sets offer easy installation, long-distance connectivity, and dependable performance for mini-split air conditioning systems.
