Installation Notes and Tips

Verify the end sizes and flare types before installation: 3/8 in. bubble flare on one end and 16 mm male inverted flare on the other. This fitting is listed for from-gear return line applications, with one 2000 Honda Civic listing noted as return tube from gear. Match the vehicle year, model, and steering line configuration exactly before ordering. The Sunsong 3604030 is a straight fitting, so confirm routing and clearance during service.

Quality Assurance

This fitting is manufactured from high-grade steel and electroplated with zinc to improve resistance to corrosion and rust in demanding road conditions. That construction supports long-term service in areas exposed to moisture, salt, and grime.
