#4 90-Deg Crimp Hose Fitting

The #4 90-Deg Crimp Hose Fitting from FRAGOLA is engineered for high-performance automotive and motorsport fuel and fluid systems where reliability under pressure is non-negotiable. This 90-degree adapter connects 4 AN hose lines at a right angle, making it essential for custom engine bay layouts where space is tight and routing demands precision. Whether you're building a fuel injection system, coolant circuit, or brake line assembly, this fitting provides the directional flexibility needed to integrate clean, professional-grade hose runs without sharp bends that compromise flow or durability.

Constructed from lightweight aluminum with black anodized finish, the #4 90-Deg Crimp Hose Fitting delivers corrosion resistance and durability in underhood environments. The sport-crimp design accommodates 4 AN hose with a barbed inlet and female swivel outlet, allowing for tool-free directional adjustment after installation while maintaining a secure, sealed connection. The swivel end compensates for minor misalignment and vibration, reducing stress on hose ends and extending system lifespan in high-vibration applications common in modified engines, turbocharged builds, and race-prepared vehicles.

This fitting is ideal for fabricators, engine builders, and enthusiasts assembling custom fuel systems, cooling circuits, or hydraulic lines in street rods, drag cars, and high-performance street machines. The 90-degree configuration eliminates the need for multiple 45-degree fittings, reducing potential leak points and simplifying installation in confined spaces around cylinder heads, intercoolers, or fuel rails. Pair this fitting with quality 4 AN hose and matching FRAGOLA components for a complete, OEM-quality system capable of handling fuel injection pressures, boost cooling, and aggressive track use without compromise.
