#6 X 45 Bulkhead Black

The #6 X 45 Bulkhead Black by FRAGOLA is a precision hydraulic fitting designed for professionals who demand reliable fluid transfer in high-performance fuel and coolant systems. This compact bulkhead connector serves as a critical junction point in custom engine builds, fuel injection setups, and cooling circuit modifications where space is limited but reliability cannot be compromised. Whether you're routing fuel lines through a firewall, integrating auxiliary coolers, or plumbing a custom supercharger cooling loop, this fitting ensures leak-free performance under demanding conditions.

Manufactured by FRAGOLA—a trusted name in motorsports plumbing—the #6 X 45 Bulkhead features a black anodized aluminum construction that resists corrosion and withstands extreme underhood temperatures common in turbocharged and supercharged applications. The #6 designation indicates a 3/8-inch AN hose connection, a standard in competitive and street performance builds. The 45-degree bulkhead design allows flexible routing through tight engine bays while maintaining structural integrity; the angled configuration reduces stress on hose barbs and minimizes kinking, ensuring consistent fluid flow rates whether transferring fuel at 45+ PSI or coolant in high-temperature circuits.

This bulkhead excels in custom fuel system installations, including carbureted hot rods, fuel-injected swaps, and forced-induction setups where penetrating a panel or firewall is essential. Its compact footprint (3 × 1 × 5 inches) and lightweight construction (0.04 lbs) make it ideal for weight-conscious builds without sacrificing durability. Installation is straightforward: thread the fitting into a pre-drilled hole, apply appropriate thread sealant, and secure with a wrench on the hex body. Compatible with standard -6 AN hose and fittings, it integrates seamlessly into any motorsports cooling or fuel infrastructure, making it an indispensable component for engine builders, fabricators, and enthusiasts performing extensive vehicle modifications.
