#4 Female Swivel to Male 90 Degree Fitting

The FRAGOLA #4 Female Swivel to Male 90 Degree Fitting is a precision-engineered hose adapter designed for high-performance fuel, oil, and coolant line applications in custom automotive builds and engine modifications. This fitting serves as a critical junction point in fuel systems, engine bay plumbing, and transmission cooling setups where directional changes and secure connections are essential.

Constructed with FRAGOLA's reputation for quality aerospace-grade materials and meticulous tolerances, this fitting features a female swivel inlet that accepts standard #4 hose ends while delivering a male 90-degree outlet for seamless integration into your system. The swivel design eliminates stress on hose fittings during installation and vibration cycles, reducing fatigue failure and the risk of leaks at connection points—critical in high-vibration engine bays and forced-induction builds.

This fitting is ideal for fabricators, engine builders, and street/track enthusiasts constructing custom fuel systems, intercooler plumbing, and more. Its compact design ensures it fits cleanly in confined spaces without adding unnecessary bulk or weight to your platform, making it a valuable addition to any automotive project.
