#10 Female 90 Degree Coupler Fitting Black

The #10 Female 90 Degree Coupler Fitting Black (model 496310-BL) is a precision hydraulic adapter engineered for high-pressure fuel and fluid transfer systems in performance automotive builds. Designed by FRAGOLA, a trusted manufacturer of braided hose and fitting solutions, this 90-degree coupler connects two #10 AN female swivel ports at a right angle, making it essential for tight engine bay layouts where space constraints demand unconventional line routing. Whether you're plumbing a fuel system in a custom drag car, setting up bypass or return lines on a turbocharged platform, or routing coolant in a supercharged engine, this fitting eliminates the need for multiple angled hose bends that weaken structural integrity and invite leaks.

Constructed from aluminum and finished in black anodize, the 496310-BL delivers corrosion resistance and a professional appearance in show-quality engine compartments. The dual #10 AN female swivel design accommodates standard braided hose fittings on both ports, allowing 360-degree swivel action that reduces vibration stress and simplifies installation when hose alignment isn't perfectly linear. Black anodizing protects against oxidation in both street and racing environments, while the aluminum body keeps weight minimal—critical in performance platforms where every ounce affects handling and acceleration. The coupler's compact footprint (3.85 x 1.05 x 5.45 inches) fits alongside headers, turbo manifolds, and firewall-mounted fuel cells where off-the-shelf 90-degree hose adapters won't clear adjacent components.

Mechanics and fabricators working on LS swaps, small-block modifications, and custom fuel system builds rely on this fitting to eliminate plumbing conflicts without compromising flow or reliability. Install it inline between braided hose sections using standard -10 AN hose crimps and ferrules—no special tools required beyond a wrench for the swivel engagement. This coupler handles both fuel and coolant applications across street, strip, and road racing builds, making it an indispensable stock item for any shop running multiple high-performance projects. Verify your hose termination style (#10 AN female swivel) and pressure rating requirements before ordering to ensure seamless integration into your existing system.
