6AN to 8AN O-Ring Port Adapter Blue Male Male

The 6AN to 8AN O-Ring Port Adapter Blue Male Male from REDHORSE PERFORMANCE is a precision hose fitting designed for fuel systems, oil coolers, and hydraulic circuits in modified vehicles. This adapter bridges different line sizes, allowing you to downsize from an 8AN port to a 6AN hose without compromising seal integrity or system efficiency.

Built for engine builders, tuners, and serious enthusiasts who demand reliability under high-pressure conditions, this component solves common plumbing challenges when adapting aftermarket fuel rails, filter housings, or remote-mounted fuel pumps to existing infrastructure. The dual male thread configuration with O-ring face seals delivers leak-free performance across boost and pressure cycles typical of turbocharged and supercharged builds, while the anodized blue aluminum construction provides both corrosion resistance and visual identification on crowded engine bays.

This adapter suits fuel system downsizing on EFI swaps, custom fuel cell installations, and engine platform conversions where original manifolds or filter blocks feature 8AN ports but your hose library or pump outlet is standardized at 6AN. Compatibility spans a variety of aftermarket applications, ensuring reliable performance in demanding environments.
