The Straight Hose Fitting -3AN from Vibrant Performance is a precision-engineered hydraulic adapter designed for custom fuel, coolant, and transmission fluid lines in modified vehicles. This fitting serves as the critical connection point between -3AN PTFE braided hose and -3AN female port receivers, making it essential for builders constructing fuel systems, turbo intercooler plumbing, and engine cooling upgrades. Whether you're installing a custom fuel rail on a tuned engine or routing high-pressure coolant lines through a performance build, this straight fitting delivers dependable leak-free connections where precision matters.
Manufactured from aluminum and finished in black anodized coating, the straight hose fitting resists corrosion while maintaining a clean appearance in engine bays and under-vehicle installations. The -3AN designation refers to a 3/16-inch nominal bore diameter, a standard in performance hydraulics that balances flow capacity with packaging constraints in tight engine compartments. The straight configuration eliminates bends, reducing turbulence and pressure drop—critical for fuel delivery consistency and thermal efficiency. PTFE hose compatibility ensures the fitting handles high-temperature and high-pressure applications without degradation, making it suitable for both naturally aspirated and forced-induction builds.
Mechanics and engine builders rely on Vibrant Performance fittings for custom fuel systems, intercooler setups, and modified coolant circuits where OEM components fall short. The -3AN size strikes the ideal balance for mid-range performance applications—offering enough flow for carbureted and EFI fuel systems without oversizing lines in compact engine bays. Installation requires a simple push-fit connection to -3AN PTFE hose and thread-in attachment to -3AN female receivers; proper hose crimping and fitting torque ensure long-term reliability. This fitting is sold individually, allowing builders to purchase only the quantity needed for their specific plumbing layout.
