12AN 90Deg Male Bulkhead Adapter Black

The 12AN 90Deg Male Bulkhead Adapter Black from REDHORSE PERFORMANCE is a precision hydraulic fitting engineered for custom fuel, oil, and coolant line routing in high-performance vehicle builds. This bulkhead adapter allows you to transition AN hose connections through panel walls or firewall penetrations while maintaining a clean, professional appearance and full system integrity. Whether you're fabricating a custom fuel system for a turbocharged engine bay, routing oil cooler lines, or installing a remote oil filter setup, this 90-degree male adapter handles the demanding requirements of modern street and race car modifications.

Manufactured from aerospace-grade materials, the 12AN 90Deg Male Bulkhead Adapter features a 90-degree elbow geometry that reduces flow turbulence and minimizes pressure losses compared to dual-hose configurations. The bulkhead design incorporates a flanged connection for secure wall mounting with minimal protrusion—critical when space constraints in modern engine compartments demand compact solutions. Black anodized finish resists oxidation and delivers corrosion resistance in harsh under-hood environments, ensuring longevity even under sustained heat and vibration. The male AN12 thread pattern accepts standard -12 AN hose with JIC fittings, guaranteeing compatibility with industry-standard fuel system components and aftermarket performance lines.

This adapter benefits enthusiasts building fuel-injected engine swaps, turbo installations, and custom cooling solutions where factory routing doesn't support modern performance requirements. Installation is straightforward—mount the bulkhead flange from the engine bay side, then connect your -12 AN hose directly to the male port. The compact 3.9 x 1.55 x 5.45 inch profile fits tight spaces behind shock towers and firewall penetrations. Verify your firewall thickness (typically 0.125–0.250 inch) and confirm hose routing clearance before final fabrication; the 90-degree angle eliminates sharp bends that can restrict flow or compromise hose life in high-pressure fuel systems rated for 60+ PSI.
