Tube to Female AN Adapte 1/4in Tube OD to -4AN

The Tube to Female AN Adapter 1/4in Tube OD to -4AN from Vibrant Performance is a precision fluid-line adapter engineered for custom fuel, coolant, and brake system builds where tubing-based plumbing meets standardized AN fittings. Whether you're fabricating a custom fuel cell installation, upgrading brake lines on a track car, or integrating aftermarket cooling systems, this adapter bridges the gap between rigid tubing and quick-disconnect AN components. It's an indispensable connector for serious engine builders and fabricators who demand reliability under pressure.

This adapter accepts 1/4-inch outer-diameter tubing and threads into a female -4AN port, maintaining full flow capacity while ensuring leak-free connections under high-pressure conditions. Vibrant Performance's precision machining guarantees tight tolerances and compatibility with industry-standard AN thread specifications, critical for applications where fluid loss or pressure drop is unacceptable. The compact 3.54-inch length and minimal 0.04-pound weight make it ideal for tight engine compartments where space and weight savings matter. The adapter's robust construction handles fuel, oil, coolant, and hydraulic fluid applications, making it a versatile solution for multiple system configurations.

Fabricators, performance shops, and DIY builders working on fuel injection conversions, custom cooling loops, and brake system overhauls benefit most from this adapter's reliability and simplicity. Installation requires no special tools beyond standard wrenches—straightforward hand-tightening with a backup wrench prevents over-torque and ensures a clean seal. Compatibility spans virtually any tubing-fed system where AN standardization is preferred, from street machines to full race builds. Pair this with quality hose clamps and Teflon tape to guarantee dependable performance across thousands of miles or track sessions.
