8AN Male to 8AN 0-ring Port Adapter Clear

The 8AN Male to 8AN 0-ring Port Adapter Clear from REDHORSE PERFORMANCE is a critical fitting component for custom fuel and coolant systems in high-performance vehicles. This adapter serves as the bridge between 8AN hose lines and 8AN O-ring boss ports on fuel rails, intercoolers, and turbo manifolds. Whether you're building a full fuel system upgrade or installing a custom cooling loop, this clear adapter enables seamless, leak-free connections.

Constructed with REDHORSE PERFORMANCE's precision engineering, the 8AN male fitting mates directly into 8AN O-ring ports using a sealing O-ring design that eliminates thread sealant dependency and provides superior vibration resistance under high-pressure conditions. The clear anodized aluminum finish allows visual inspection of fluid flow and system integrity, a feature preferred by engine builders and tuners who need to monitor for air pockets or contamination in fuel and coolant circuits.

This fitting is essential for LS engine conversions and modular engine builds, delivering reliability where aftermarket modifications demand it. It works seamlessly with REDHORSE hose lines and is ideal for vehicles running custom fuel systems or secondary cooling circuits.
