#4 90 Deg Union Fitting Black

The FRAGOLA #4 90 Deg Union Fitting in Black is a precision aluminum adapter designed for high-pressure fluid transfer systems requiring reliable 90-degree directional changes. This 4 AN male-to-male connector delivers the directional control necessary in fuel, oil, coolant, and hydraulic applications where space constraints or component layout demand angled connection points rather than straight fittings.

Built from aluminum and finished in black anodize, this union fitting provides corrosion resistance and durability in engine bays, race fuel systems, and performance vehicle builds. The black anodized coating protects against oxidation and UV exposure while maintaining a professional appearance in visible installations. Both ends accept standard 4 AN hose fittings, allowing seamless integration into existing line configurations without requiring adapters at connection points.

This fitting addresses a common layout challenge in tight engine compartments, fuel cell plumbing, and custom cooling systems where straight connectors create routing conflicts or excessive hose bends. The 90-degree angle reduces hose stress compared to forced bends, extending line life and reducing leak risk at connection points. Precision-machined threads ensure leak-free seals when properly installed with appropriate PTFE tape or thread sealant, meeting the standards of high-performance automotive, marine, and small-engine applications requiring dependable fluid management.
