#3 Female T-Swivel on Run Fitting Black

The #3 Female T-Swivel on Run Fitting Black from FRAGOLA is a precision adapter tee designed for custom hydraulic and fuel line systems in modified vehicles. This fitting serves as a critical junction point where three AN-sized lines converge, making it indispensable for high-performance engine builds, turbo installations, and complex fuel delivery setups. Whether you're upgrading a street rod, race car, or heavily modified daily driver, this T-swivel adapter provides the flexibility needed to route lines cleanly while maintaining structural integrity under pressure.

Constructed from aluminum and finished in black anodize, the #3 Female T-Swivel on Run Fitting Black features a female swivel connection on one branch and dual male ports on the remaining run, allowing oil, fuel, or coolant to branch efficiently without dead legs or pressure loss. The swivel design accommodates vibration and thermal expansion common in turbocharged and supercharged applications, reducing stress on hose assemblies and fittings. FRAGOLA's aluminum construction keeps weight minimal—critical for competition vehicles—while the black anodized finish resists corrosion and maintains a clean appearance in engine bays where aesthetics matter.

This adapter is ideal for fabricators and enthusiasts building custom fuel rails, turbo oil return lines, or complex cooling circuits where standard fittings fall short. Installation requires standard AN hose crimpers and proper torque technique to prevent leaks under load. The compact 2.2 x 0.85 x 4.2 inch footprint fits tight engine compartments, making it popular in street performance and endurance racing builds. Verify your line sizing and pressure rating before purchase to ensure compatibility with your specific modification project.
