#12 90-Degree Female Couple Fitting

The FRAGOLA #12 90-Degree Female Couple Fitting is a precision adapter designed for high-pressure fluid transfer systems in motorsports, hydraulic racing applications, and fuel delivery circuits. This 12 AN female swivel-to-12 AN female swivel elbow fitting enables compact routing of fuel, oil, and coolant lines in tight engine compartments while maintaining leak-free connections under demanding conditions.

Constructed from aluminum and finished in blue anodized coating, this coupling delivers corrosion resistance and lightweight performance—critical factors in high-heat and salt-air environments. The 90-degree geometry allows plumbers and technicians to navigate around engine blocks, suspension components, and firewall barriers without requiring long straight runs of hose. The swivel design on both ends accommodates minor misalignment and vibration, reducing stress on adjacent fittings and extending system service life. Weighing just 0.26 lbs, this compact adapter minimizes added weight while maintaining the structural integrity required for sustained pressure cycles in racing fuel systems, turbo oil supply lines, and engine coolant loops.

This fitting is engineered for users building custom hydraulic circuits, restoring vintage race vehicles, or upgrading fuel delivery systems in performance engines. The AN12 size handles the flow demands of fuel injection systems and high-volume oil cooling circuits found in track-day cars, dragsters, and street rods. Serious builders choose FRAGOLA adapters for their precise manufacturing tolerances and proven reliability across thousands of racing hours. Whether you're routing lines through a tight engine bay or replacing a compromised fitting in an established system, this 90-degree couple provides the durability and fitment precision expected in competition-grade applications.
