3/8" x 3/4" x 3/8" 25' Copper Line Set

Streamline® 61280250 – 3/8" OD x 25 ft Refrigeration-Grade Copper Tube Coil, Nitrogen-Charged Streamline® 61280250 is a 25-foot coil of refrigeration-grade copper tubing with a 3/8-inch outside diameter. Manufactured from seamless UNS C12200 copper, this tube is designed for HVAC and refrigeration systems requiring high-pressure capabilities and compliance with ASTM B280 standards. Each coil is internally charged with nitrogen during production to inhibit oxidation and maintain internal cleanliness. The tube supports a working pressure of up to 700 psi and is suitable for refrigerants such as R-410A and R-32. Its corrosion-resistant properties and smooth interior surface support long-term system efficiency and performance integrity in residential and light commercial applications.
