3/8" x 5/8" x 3/8" 50' Copper Line Set

Streamline® 61080500 – 3/8" x 3/4" x 50 ft Insulated Copper Line Set for HVAC Applications The Streamline® 61080500 line set consists of a 3/8-inch liquid line and a 3/4-inch suction line, both 50 feet in length and constructed from seamless, nitrogen-purged UNS C12200 copper. It meets ASTM B280 standards, making it suitable for high-pressure HVAC and refrigeration systems, including those using R-410A and R-32 refrigerants. Each tube is factory-insulated with a 1/2-inch wall closed-cell polyethylene foam and protected by a weather-resistant outer jacket to minimize thermal transfer and physical damage. The product is engineered to withstand up to 700 psi working pressure and service temperatures up to 250°F. Product Specifications Liquid Line OD: 3/8 inch Suction Line OD: 3/4 inch Length: 50 feet continuous Copper Type: UNS C12200 (phosphorus-deoxidized, high residual phosphorus) Internal Treatment: Nitrogen-charged to prevent oxidation during storage Insulation: 1/2 in. closed-cell foam with UV-resistant jacket Pressure Rating: 700 psi maximum working pressure Temperature Rating: -40°F to 250°F Compliance: ASTM B280 refrigerant-grade standard Refrigerant Compatibility: R-410A, R-32, and other high-pressure refrigerants Application and Use This line set is suitable for use in split-system air conditioners and heat pumps, both residential and light commercial. It is designed for brazed or flared connections and should be installed in accordance with local mechanical and building codes. Pre-insulated configuration reduces field labor and improves installation consistency.
