3/8" x 3/4" x 3/8" 35' Copper Line Set

Streamline® 61280350 – 3/8" OD x 35 ft ACR Copper Coil, Nitrogen-Charged The Streamline® 61280350 is a 35-foot refrigeration-grade copper tube coil with a 3/8-inch outside diameter, manufactured for air conditioning and refrigeration system installations. This tubing is made from seamless UNS C12200 copper and meets ASTM B280 requirements for internal cleanliness, dimensional consistency, and pressure integrity. Each coil is nitrogen-purged to prevent oxidation and scale formation inside the tubing during storage and transport. The copper tube is rated for maximum working pressures up to 700 psi and temperatures up to 250°F, making it compatible with high-pressure refrigerants such as R-410A and R-32. The flexible coil form facilitates installation in tight or complex routing conditions without compromising system performance.
