#8 x 18mm x 1.5 Adapter Fitting Black

The #8 x 18mm x 1.5 Adapter Fitting in Black from FRAGOLA is a precision hose adapter designed for high-performance fuel, coolant, and hydraulic systems in modified vehicles and racing applications. This fitting bridges different port sizes and thread standards, allowing you to integrate components from various manufacturers into a cohesive fuel or cooling system. Whether you're building a custom fuel delivery setup for a turbocharged engine, upgrading a carburetor fuel system, or establishing a closed-loop cooling circuit, this adapter fitting provides the critical size transition that keeps your system sealed and efficient.

Constructed from durable anodized aluminum with a black finish, the #8 x 18mm x 1.5 Adapter Fitting resists corrosion and maintains its appearance under engine bay conditions while managing fuel or coolant flow without contamination. The #8 designation indicates JIC (Joint Industry Council) port sizing, while the 18mm thread and 1.5 pitch specify the opposite end's metric dimensions—a common configuration when adapting between SAE and metric system components. The machined construction ensures precise thread engagement, preventing leaks that could compromise engine performance or safety in high-pressure applications typical of turbocharged, supercharged, or fuel-injected builds.

Engine builders, fuel system integrators, and serious weekend warriors benefit most from this adapter when consolidating parts sourced from different suppliers or transitioning between imperial and metric standards. Installation requires compatible JIC hose ends on one side and 18mm x 1.5 metric adapters or components on the other; verify your system's pressure rating and fluid type to ensure compatibility. At just 0.05 lbs, this compact fitting adds negligible weight while solving the dimensional gaps that prevent bolt-together simplicity in custom fuel, cooling, and hydraulic circuits.
