12AN Male to 12AN Female 45Deg Black

The 12AN Male to 12AN Female 45Deg Black adapter from REDHORSE PERFORMANCE is an essential fitting for any serious performance fuel system, coolant line, or hydraulic brake upgrade. Built for automotive enthusiasts and professional mechanics who demand reliability under pressure, this 45-degree adapter enables clean routing of high-flow lines around tight engine bays and complex suspension setups. Whether you're upgrading to larger fuel injectors, installing a turbocharger feed system, or reconfiguring brake hardlines for a custom chassis, this fitting serves as the critical connector that ties your system together without leaks or restrictions.

Constructed from aerospace-grade aluminum and finished with black anodizing, the 12AN Male to 12AN Female 45Deg Black fitting resists corrosion and heat degradation even in harsh under-hood environments. The 45-degree angle design reduces stress on hose clamps and adapter ports compared to straight configurations, improving longevity and eliminating common leak points at high pressure. The swivel female end allows final line positioning without twisting the entire hose assembly, a mechanic's advantage when space is constrained. Both ends feature full 12AN (AN12) porting—a standard that flows 0.75-inch ID hose at peak efficiency—making this adapter suitable for fuel delivery on turbocharged applications, high-capacity cooling circuits, and modern EFI fuel return lines.

This adapter is ideal for fabricators building custom fuel cells, restorers installing period-correct fuel injection kits, and performance tuners consolidating aftermarket plumbing systems. Its compact footprint (2.85 x 1.4 x 3.8 inches) and lightweight design (0.19 lbs) make it perfect for applications where space and unsprung weight matter—from drift builds to road racing platforms. Compatible with all standard 12AN hose and male/female AN fittings, the REDHORSE Performance fitting integrates seamlessly into existing plumbing without requiring adapter chains. For leak-free, pressure-rated connections that stand up to boost, vibration, and temperature cycles, this black anodized adapter delivers proven performance.
