#12 Flare #8 Flare Reducer Black

The #12 Flare to #8 Flare Reducer in Black from AEROQUIP is a precision hydraulic fitting designed for custom fuel, brake, and cooling system installations where tube diameter reduction is required. This adapter bridges the gap between larger #12 (3/4-inch) and smaller #8 (1/2-inch) JIC flare connections, making it indispensable for engine swaps, fuel system upgrades, and high-performance modifications where stock plumbing doesn't align with aftermarket components. Whether you're building a custom hot rod, retrofitting modern fuel injection into a classic engine bay, or integrating auxiliary cooling lines, this reducer ensures leak-free connections under pressure.

AEROQUIP fittings are engineered to military and aerospace standards, using ductile iron construction with a black electroless-nickel finish that resists corrosion and withstands engine compartment heat and vibration. The dual JIC 37° flare design ensures a dependable metal-to-metal seal that handles pump discharge pressures, fuel rail volumes, and thermal cycling without weeping or failure. The compact 3.4 x 1.85 x 5.25-inch profile and lightweight 0.15-pound construction allow flexible integration into tight engine compartments while maintaining structural integrity under load and vibration typical of high-boost or high-RPM applications.

This fitting suits fabricators, engine builders, and DIY enthusiasts tackling fuel system, hydraulic brake, or coolant system work on street rods, LS swaps, turbo setups, and vintage restorations. Installation requires no special tools beyond a flare wrench; simply hand-tighten, then snug to manufacturer torque spec using two wrenches to prevent tube rotation. Compatible with all JIC-standardized flare tubing and fittings, the #12 to #8 reducer pairs seamlessly with OEM and aftermarket hydraulic and fuel components, making it a reliable solution for any custom automotive application demanding dependable fluid delivery.
