Male -6AN to Male 3/8in NPT 90 Degree Fitting

The Male -6AN to Male 3/8in NPT 90 Degree Fitting from Vibrant Performance is a critical adapter for fuel, oil, and coolant line routing in performance and custom engine builds. When running aftermarket fuel systems, turbocharger feed lines, or remote oil filtration setups, mismatched port configurations often force builders to source quality adapters that reliably bridge AN hose standards with NPT threaded ports on blocks, heads, and components. This 90-degree fitting eliminates the need for separate elbows and reducers, saving space in tight engine bays while maintaining system integrity under pressure.

Constructed from durable aluminum alloy, this adapter features a -6AN male connection on one end (compatible with standard -6 braided hose) and a 3/8-inch NPT male thread on the other, with the 90-degree elbow design directing flow perpendicular to the main line run. The tight 90-degree angle minimizes pressure loss at the junction, critical for maintaining proper fuel pressure in carbureted or EFI applications where even slight losses compound across multiple fittings. Vibrant Performance's precision machining ensures consistent thread engagement and leak-free seals when paired with appropriate thread sealant or O-ring adapters, meeting the reliability demands of high-flow systems and extended track use.

This fitting benefits engine swap projects, fuel cell installations, and custom plumbing where factory -AN ports don't align with engine-mounted NPT fittings. Mechanics working on LS engine conversions, turbo fuel supply lines, and remote catch-can systems will find this adapter indispensable for routing hoses around headers, manifolds, and firewall constraints. It complements any Vibrant Performance line component and works seamlessly with standard -6AN hose fittings, making it a versatile choice for street and competition builds requiring clean, compact plumbing solutions.
