8AN Male to 12AN O-ring Port Adapter Black

The 8AN Male to 12AN O-ring Port Adapter in Black from Redhorse Performance is a crucial hydraulic hose fitting designed for fuel system upgrades, coolant lines, and high-pressure fluid transfer applications in modified vehicles. This adapter is ideal for technicians and engine builders who require reliable connections in complex fuel delivery and cooling systems.

Constructed from black anodized aluminum, this adapter resists corrosion and maintains structural integrity under extreme temperatures and vibrations. The o-ring sealed design eliminates the need for PTFE tape or thread sealant, providing a secure connection that is essential for high-performance applications. The adapter bridges two critical AN port sizes with precision-engineered tolerances, ensuring compatibility between components.

This adapter is particularly beneficial for turbocharged, supercharged, and naturally aspirated builds where fuel supply lines must transition between fuel pump assemblies and high-flow fuel rails or carbureted fuel blocks. It allows seamless integration between components of different port sizes without compromising flow rate or system pressure ratings, making it an excellent choice for custom plumbing solutions.
