These 3/8 in. pure copper street elbow fittings are designed to deliver reliable, long-lasting performance in HVAC, refrigeration, and ACR air conditioning line set applications. Each fitting features a 90-degree long turn radius design that allows for smooth directional changes in your copper tubing runs, reducing flow restriction and minimizing stress on the line.

Crafted from pure copper, these fittings offer excellent thermal conductivity and corrosion resistance, standing up to the demands of refrigerant systems over time. The long turn radius design also helps protect tubing integrity by reducing sharp bends that can weaken the line.
