#4 X 45 Bulkhead Black

The #4 X 45 Bulkhead Black from FRAGOLA is a 45-degree aluminum bulkhead fitting designed for high-performance hydraulic and fluid transfer systems. This fitting serves applications where space constraints or system geometry require an angled connection rather than a straight pass-through, making it essential for custom plumbing layouts in motorsports, industrial hydraulics, and specialized equipment builds. Whether you're assembling a race car's fuel or cooling system, routing brake lines in tight engine bays, or designing custom fluid pathways, this bulkhead adapter provides a reliable solution for systems operating under pressure.

Constructed from lightweight aluminum and finished in durable black anodizing, the #4 X 45 Bulkhead Black features dual 4 AN male connections—one on the bulkhead mounting face and one angled at 45 degrees—allowing you to penetrate a panel or firewall while maintaining precise directional flow control. The anodized coating resists corrosion and provides excellent durability in harsh underhood environments, while the aluminum construction keeps overall system weight minimal. The 45-degree angle geometry is critical for preventing kinks in hose runs and optimizing space utilization in engine compartments where vertical or horizontal routing alone would create installation challenges or system inefficiencies.

This bulkhead fitting is ideal for motorsports enthusiasts, custom fabricators, and hydraulic system engineers who demand precision and compatibility. The 4 AN male-to-male configuration ensures seamless integration with standard -4 AN hoses and adapters, and the compact 3.5 x 0.95 x 6.55 inch profile fits into confined mounting spaces without sacrificing flow capacity. Installation is straightforward—simply mount the bulkhead face through your panel with appropriate sealing, then connect your hose lines to the angled and perpendicular ports. FRAGOLA's reputation for manufacturing precision fittings makes this component a trusted choice for both street and race applications where reliability cannot be compromised.
