10AN to 8AN O-Ring Port Adapter Blue Male Male

The 10AN to 8AN O-Ring Port Adapter Blue Male Male from REDHORSE PERFORMANCE is an essential fitting for custom hydraulic and fuel system builds where stepped line reduction is required. Whether you're fabricating a high-flow turbo fuel system, upgrading a nitrous delivery line, or integrating remote oil coolers on a modified engine, this adapter bridges the gap between larger 10AN ports and smaller 8AN component connections.

Purpose-built for enthusiasts and fabricators who demand reliability in pressure-critical applications, this fitting eliminates the need for bulky manifolds or restrictive reducer blocks. Constructed with precision-machined aluminum and sealed by dual O-ring technology, the 10AN to 8AN male-to-male design ensures leak-free performance under sustained pressure cycles. The anodized blue finish provides corrosion resistance while serving as a visual identification marker in complex plumbing layouts.

This adapter suits street rod builders, drag racing platforms, road course competitors, and forced-induction tuners who run aftermarket fuel rails, fuel surge tanks, or pressure-regulated distribution blocks. Its compact design minimizes footprint while maximizing performance, making it a reliable choice for managing multiple fuel, coolant, or oil circuits in tight engine bays.
