90 Degree Fitting Tight Radius -12AN

The 90 Degree Fitting Tight Radius -12AN from Vibrant Performance is a precision hose adapter engineered for high-flow fuel, coolant, and brake systems in street rods, performance engines, and custom automotive builds. This fitting addresses the core challenge every serious engine builder faces: routing lines through tight engine compartments without compromising flow rate or reliability. The tight-radius design minimizes dead zones and turbulence while maintaining the structural integrity required for high-pressure applications.

Constructed from aluminum with precision-machined internal passages, this 90-degree adapter delivers consistent flow characteristics across a wide temperature range. The -12AN port size accommodates standard braided stainless steel hose and swaged fittings, common throughout performance fuel and cooling systems that operate at sustained pressures between 40 and 100 PSI. The tight-radius geometry reduces overall footprint by approximately 15% compared to standard 90-degree fittings, making it invaluable when working around header tubes, manifold castings, and factory anchor points in confined underhood environments.

Mechanics and fabricators building LS engine swaps, turbo fuel systems, or custom water cooling circuits rely on Vibrant Performance fittings to eliminate leaks and maintain clean routing. This adapter integrates seamlessly with any -12AN hose assembly and works equally well in fuel return loops, transmission coolers, and intercooler plumbing. Installation requires standard hose clamps or swaged fittings; no special tools are needed. The compact 5.51 x 1.5 x 6.3 inch profile and 0.3 lb weight ensure minimal impact on weight distribution while maximizing packaging efficiency in space-critical applications.
