Product Overview – 82 ft Refrigeration Copper Pipe for HVAC Systems
This 82 ft refrigeration copper pipe is engineered for demanding HVAC and refrigeration applications where reliable refrigerant circulation and durable tubing are required. The 82 ft length provides flexibility for longer line runs between indoor and outdoor units.
3/8" liquid line for refrigerant feed
7/8" suction line for refrigerant return
82 ft / 25 m long refrigerant line tubing
Premium copper tubing for HVAC and refrigeration systems
Designed for stable refrigerant flow and efficient heat transfer
Suitable for residential, commercial, and light industrial HVAC projects
Copper is widely used in HVAC refrigerant lines because it offers strong thermal transfer performance, good flexibility, pressure resistance, and corrosion resistance in long-term cooling and heating applications.
What Does 3/8" x 7/8" Refrigeration Copper Pipe Mean?
3/8" Liquid Line
The 3/8 inch copper tube is usually used as the liquid line. It carries high-pressure liquid refrigerant from the outdoor condenser to the indoor evaporator or refrigeration unit.
7/8" Suction Line
The 7/8 inch copper tube is usually used as the suction line. It returns low-pressure refrigerant vapor back to the compressor and supports larger refrigerant volume in higher-capacity systems.
82 ft Length for Extended HVAC Installations
The 82 ft length is suitable for installations where indoor and outdoor units are installed farther apart. A longer continuous line set can reduce the need for extra joints and help lower refrigerant leakage risk.
