#8 x 3/4-16 90 Deg Swivel Adapter Black

The #8 x 3/4-16 90 Deg Swivel Adapter Black from FRAGOLA (model 499208-BL) is a precision-engineered hydraulic fitting designed for high-performance automotive cooling, fuel, and brake line systems where directional flexibility is essential. This adapter solves a critical challenge in vehicle modification and engine bay layout optimization: routing hoses around tight spaces, engine components, and firewall penetrations without kinking, pinching, or compromising system integrity. Whether you're building a custom cooling loop, upgrading fuel delivery on a modified engine, or reconfiguring brake lines during a frame-off restoration, a 90-degree swivel adapter is non-negotiable for clean, reliable installations.

This adapter features an 8 AN (5/8-inch) male O-ring swivel fitting on both ports, allowing 90-degree directional changes while maintaining a full, unrestricted flow path through the center bore. The black anodized aluminum construction provides excellent corrosion resistance in underhood environments while keeping weight minimal—a key consideration in performance builds. The O-ring face seal (OFS) design ensures leak-free connections without thread sealant; the swivel mechanism allows hose rotation after installation, eliminating the need for repositioning the entire line assembly during final fitment. At just 0.1 lbs and measuring 1.95 x 1.55 x 4 inches, this compact fitting tucks seamlessly into constrained engine bays without adding bulk or requiring additional brackets.

Mechanics, fabricators, and enthusiasts building turbocharged, supercharged, or heavily modified vehicles rely on these adapters to navigate complex hose routing scenarios—from intercooler piping to remote oil coolers, fuel injection upgrades, and custom cooling systems. The 8 AN size handles flow volumes typical of high-output engines without introducing excessive pressure drop. Compatibility is straightforward: any system using 8 AN hose ends, AN fittings, or banjo bolts will connect directly; the swivel feature accommodates both 45- and 90-degree approach angles, making it ideal for retrofit work where original line geometry doesn't match new component placement. Installation is straightforward—hand-tighten the swivel until snug, then use a wrench to lock the body in place, leaving the rotating end free for final hose alignment before full tightening.
