-8AN to 16mm x 1.5 Metri c Straight Adapter

The -8AN to 16mm x 1.5 Metric Straight Adapter is an essential component for custom fuel, coolant, and hydraulic line routing in high-performance engine builds and modified vehicle systems. This adapter bridges the gap between AN (Army-Navy) fittings—the industry standard in motorsports fuel delivery and turbo plumbing—and metric threads commonly found on OEM components, foreign imports, and aftermarket European-sourced parts.

Whether you're fabricating a fuel rail system, integrating an auxiliary cooling loop, or adapting metric brake or power steering components into an AN-based platform, this straight adapter ensures leak-free connections without additional elbows or reducers. Engineered for direct thread-to-hose connection, the -8AN to 16mm x 1.5 Metric Straight Adapter features a male 16mm x 1.5 metric thread on one end and a standard -8AN male fitting on the other, allowing seamless integration into systems running pressures typical of fuel delivery, coolant circulation, and turbocharger intercooler applications.

Compact dimensions (3.05 x 1 x 3.5 inches) and a verified weight of 0.04 lbs make it easy to route in tight engine bays without adding complexity or failure points. The metric thread pitch of 1.5mm ensures secure engagement with OEM and aftermarket metric components, while the -8AN side maintains compatibility with braided stainless steel hoses, rigid aluminum tubing, and standard AN push-lock and JIC fittings found throughout professional motorsports plumbing.
