#3 x 90 Deg Bulkhead Fitting Black

The FRAGOLA #3 x 90 Deg Bulkhead Fitting Black (MPN 483303-BL) is a precision-engineered aluminum bulkhead connector designed for high-pressure fluid line applications in custom hydraulic and fuel systems. This 90-degree fitting accepts dual 3 AN male threads and provides a compact junction point where lines must transition at a right angle through a panel, firewall, or bulkhead—a critical requirement in racing, off-road, and marine propulsion setups where space efficiency and leak-free connections are non-negotiable.

Machined from aluminum and finished in black anodize, this bulkhead fitting resists corrosion while maintaining a clean, professional appearance in engine bays and custom installations. The 90-degree angle geometry allows two perpendicular 3 AN lines to mate cleanly without external routing around sharp corners, reducing overall system complexity and component count. AN fittings conform to established aerospace fluid transfer standards, ensuring compatibility with other quality hoses and adapters across the market. The black anodized surface provides both aesthetic consistency and a protective oxide layer that guards against oxidation in both dry and moist environments.

This bulkhead fitting serves custom hot rods, off-road vehicles, high-performance marine engines, and hydraulic brake or fuel systems where compact 90-degree line transitions are required. Technicians and builders select bulkhead fittings specifically to penetrate barriers (firewalls, fuel cell walls, transmission tunnels) while maintaining sealed, pressure-rated connections on both sides. The 3 AN size handles flow rates typical of fuel injection, return lines, and moderate-pressure hydraulic circuits in performance applications.
