12AN to 12AN O-Ring Port Adapter Black Male Male

The 12AN to 12AN O-Ring Port Adapter Black Male Male from Redhorse Performance is an essential component for high-performance fuel system plumbing, custom engine builds, and turbocharger installations. This male-to-male adapter connects two -12 AN hose lines or ports with a secure, leak-free interface, eliminating the need for additional fittings or bulky manifolds.

Engineered from premium materials with a black anodized finish, the 12AN O-ring port adapter utilizes redundant O-ring sealing technology to prevent fuel weeping at connection points—critical in high-flow applications where vibration and thermal cycling stress conventional crush washers. The male-to-male configuration allows direct connection between two female-port components, such as fuel filter heads, regulators, or distribution blocks, without requiring intermediate adapters.

This adapter is ideal for fabricators, professional tuners, and enthusiasts building custom fuel systems for turbocharged and supercharged applications. Its lightweight design simplifies installation while maintaining full -12 AN flow capacity, ensuring your fuel delivery system operates efficiently during demanding conditions.
