6AN Male to 12AN O-ring Port Adapter Black

The 6AN Male to 12AN O-ring Port Adapter Black from REDHORSE PERFORMANCE is an essential fitting component for custom fuel, coolant, and hydraulic systems in modified vehicles. This adapter allows you to connect smaller 6AN hose lines to larger 12AN port receivers on fuel rails, manifolds, or engine blocks, ensuring proper flow capacity while maintaining system integrity.

Constructed with precision engineering, the 6AN Male to 12AN O-ring Port Adapter features a robust black anodized aluminum construction that resists corrosion and thermal cycling common in engine bays. The male 6AN end threads securely into the female 12AN port, while the integrated O-ring seal eliminates the need for additional Teflon tape, providing a leak-proof connection under pressure.

This adapter is particularly beneficial for builders working with LS swaps, turbo fuel system upgrades, and custom cooling loops where OEM port sizes don't align with aftermarket hose selections. Common applications include fuel distribution blocks and water pump bypass lines, making it a versatile choice for various automotive projects.
