Bulkhead Adapter 90 Degree Elbow -12AN

The Bulkhead Adapter 90 Degree Elbow -12AN from Vibrant Performance is a precision hose fitting designed for custom fuel, oil, coolant, and transmission line routing in high-performance engine builds. This component solves the challenge of fitting hydraulic lines through firewall penetrations or tight engine bay spaces where straight runs are impossible. Whether you're building a fuel cell system, installing a remote oil cooler, or designing custom forced induction plumbing, this adapter provides the directional change needed without sacrificing flow integrity or requiring adapter stacking.

This bulkhead adapter features a 90-degree elbow geometry with -12AN (AN12) port threads, machined from aluminum alloy for weight savings and corrosion resistance. The integrated bulkhead design allows installation directly into firewall or panel mounting points, eliminating external brackets and reducing clutter in the engine compartment. The -12AN port size handles flow rates up to approximately 200 gallons per hour at safe velocities, making it suitable for naturally aspirated and turbocharged applications. Vibrant Performance's precision threading ensures leak-free connections when paired with compatible -12AN hose ends and fittings, critical for systems carrying fuel or pressurized fluids.

Professional engine builders and enthusiasts favor this adapter for custom fuel injection systems, aftermarket oil cooler installations, and radiator bypass plumbing on modified engines. It's equally valuable for transmission cooler lines on performance vehicles requiring non-factory routing through the firewall. The compact 4.53-inch length and lightweight 0.22-pound design mean minimal space intrusion while maintaining structural integrity under pressure. Installation requires drill or pre-existing -12AN threaded bulkhead holes; verify your mounting location can accommodate the 90-degree exit angle before purchase to ensure proper hose clearance and aesthetic fitment in your engine bay layout.
