Male -6AN Male to 5/16in Hose Barb Fitting

The Male -6AN Male to 5/16in Hose Barb Fitting is an essential adapter for custom fuel, coolant, and fluid transfer systems in performance and modified vehicles. This compact yet durable fitting bridges the gap between modern -6AN AN (Army-Navy) line standards and legacy 5/16-inch barbed hose connections, making it invaluable for engine swaps, fuel system upgrades, and custom plumbing applications.

Manufactured by Vibrant Performance, a trusted name in high-performance fluid systems, this fitting features precision-machined construction that ensures a secure barb connection with minimal slippage once properly clamped. The -6AN male thread on one end accepts standard AN push-to-connect or threaded line fittings, while the 5/16-inch hose barb on the opposite end slides directly over flexible silicone or rubber hose for a mechanical grip.

Street and track mechanics rely on this fitting when modernizing older vehicles, consolidating mixed hose runs, and adapting to various plumbing configurations. It is particularly useful for those upgrading their cooling circuits or building custom fuel systems, ensuring reliable connections under pressure.
