90 Deg Adapter Fitting #4 x 1/4 MPT

The 90 Deg Adapter Fitting #4 x 1/4 MPT by FRAGOLA is a precision hydraulic and fuel line adapter designed for demanding fluid transfer applications where space and angle constraints require a compact 90-degree connection. This fitting bridges the gap between AN-standard components and NPT-threaded systems, making it essential for custom fuel systems, hydraulic lines, and high-performance engine builds where conventional straight fittings cannot accommodate tight engine compartments or complex routing requirements.

Constructed from lightweight aluminum and finished in blue anodized coating, this adapter features a #4 AN male connection (5/16-24 UNF threads) on one end and a 1/4 inch NPT male connection on the other, enabling seamless integration between different fitting standards without fluid loss or pressure degradation. The 90-degree elbow design eliminates bulky manifold blocks and reduces installation footprint while maintaining full flow capacity, and the anodized finish provides corrosion resistance in both fuel and coolant environments. Fragola fittings are engineered to SAE and JIC specifications, ensuring reliable performance under sustained pressure cycles.

This adapter is ideal for fabricators, performance technicians, and automotive enthusiasts building custom fuel delivery systems, turbo cooling lines, or hydraulic brake installations where AN and NPT components must connect in confined spaces. The compact footprint (2.1 x 1.1 x 4.1 inches) allows installation in tight engine bays, while the robust aluminum construction withstands vibration and thermal cycling. Verify port sizes and thread types on your existing lines before ordering to ensure proper fit and leak-free operation.
