Will this fitting work with standard copper tubing? I need to connect a hydraulic line to an existing setup.

While this adapter can be used in hydraulic systems, it's specifically designed to connect SAE 45-degree male ends to line, hose, or tube female ends. Make sure your copper tubing is compatible with those end types and sizes (0.4375" male and 0.25" female).
