Str Bulkhead Fitting #6

The Str Bulkhead Fitting #6 from FRAGOLA is a precision straight bulkhead connector engineered for high-pressure fluid transfer systems, including custom fuel lines, cooling circuits, and hydraulic applications. Designed for professionals and enthusiasts who demand reliable, leak-free connections in demanding environments, this fitting serves as a critical junction point where two separate fluid lines meet through a panel or bulkhead wall. The male-to-male configuration allows seamless integration into modular fuel system designs and motorsport applications where space constraints and vibration resistance are essential.

Constructed from aluminum and finished in blue anodized coating, this fitting combines lightweight durability with corrosion resistance—critical for under-hood environments and salt-spray exposure. The 6 AN (dash-6) thread size accommodates high flow rates while maintaining structural integrity under pressure cycles common in racing fuel systems, supercharger applications, and custom hydraulic builds. FRAGOLA's anodized aluminum construction reduces overall system weight compared to steel alternatives, without sacrificing strength, making it ideal for performance-oriented installations where every component is optimized for efficiency and reliability.

Engine builders, race teams, and custom automotive fabricators rely on this bulkhead fitting to create clean, professional fuel and coolant system transitions through firewall panels, manifolds, and component mounting plates. Its compact 1.5 x 1 x 4-inch profile minimizes installation footprint, while the straight design eliminates unnecessary bends that reduce flow efficiency. Compatible with all standard 6 AN hose fittings and adapters, this connector integrates seamlessly into existing fuel system architectures—whether upgrading carburetor systems to fuel injection or designing multi-circuit cooling solutions for high-output engines.
