Heat Pump - Installation Accessories

Novair Bare Copper Refrigerant Line is designed for professional heat pump and air conditioner installations requiring dependable refrigerant transfer between indoor and outdoor units. Manufactured from high-purity refrigeration-grade copper tubing, it is suitable for use with modern high-pressure refrigerants including R410A, R32, and R454B when installed in accordance with manufacturer specifications and local mechanical codes.

Copper is the industry standard for HVAC refrigerant piping due to its high thermal conductivity, corrosion resistance, durability, and compatibility with elevated operating pressures found in inverter-driven heat pump systems. Its strength-to-weight ratio and formability allow precise bending, clean routing, and long-term structural reliability in residential and light commercial applications.

This line is supplied unflaired to allow certified HVAC technicians to perform on-site flaring matched to the exact system requirements. Field flaring ensures proper seating surfaces, correct torque application, and secure mechanical connections when paired with manufacturer-approved flare nuts and torque specifications. Proper installation practices such as pressure testing and deep vacuum evacuation to micron-level standards are required to ensure system performance and longevity.

The bare copper configuration allows installers to select insulation appropriate for the climate zone and code requirements. It also provides flexibility for concealed wall cavities, line set covers, exposed mechanical runs, or custom system configurations including mini-split, ducted, and hybrid heat pump applications.

Professional installation required. Always follow applicable refrigeration codes, manufacturer guidelines, and commissioning procedures.
