3/8" x 5/8" x 3/8" 35' Copper Line Set

Streamline® 61080350 – 3/8" x 3/4" Copper Line Set, 50 ft, Insulated The Streamline® 61080350 copper line set includes a 3/8-inch outside diameter liquid line and a 3/4-inch outside diameter suction line in a 50-foot configuration. Manufactured from UNS C12200 copper and nitrogen-charged to prevent oxidation, this tubing meets ASTM B280 standards and is suitable for use in mini-split and standard split HVAC systems. Each tube is supplied pre-insulated with 1/2-inch wall closed-cell foam insulation and protected by a UV-resistant polyethylene jacket, offering thermal efficiency and resistance to environmental exposure. This configuration is designed to handle pressures up to 700 psi and temperatures up to 250°F, making it compatible with modern high-pressure refrigerants including R-410A and R-32. Product Highlights Tubing Dimensions: 3/8 in. OD (liquid), 3/4 in. OD (suction) Length: 50 feet Copper Type: Seamless, nitrogen-purged, phosphorous-deoxidized (UNS C12200) Insulation: 1/2 in. closed-cell polyethylene with weather-resistant outer jacket Rated Pressure: 700 psi working pressure Temperature Range: -40°F to 250°F Refrigerant Compatibility: Suitable for R-410A, R-32, and other HFC/HCFC systems Compliance: Conforms to ASTM B280 for refrigeration service tubing Installation Notes This line set is built for ease of routing and handling in confined or retrofit installations. It should be installed using approved brazing or flaring techniques and compatible fittings. Due to the system pressures involved, proper sealing, evacuation, and pressure testing should be performed before commissioning.
