#3 Bulkhead Tee Fitting Black

The #3 Bulkhead Tee Fitting Black from FRAGOLA is a precision hydraulic and fuel line connector designed for high-performance engine bays, custom fuel systems, and pneumatic applications where reliable flow distribution is critical. This three-way tee fitting splits or combines flow from a single inlet into two outlets—or vice versa—making it indispensable for builders who need compact, leak-free connections in tight engine compartments. Whether you're assembling a custom fuel injection system, constructing a multi-circuit hydraulic setup, or upgrading a vintage hot rod's fuel lines, this bulkhead tee provides the durability and consistent performance that professional technicians and enthusiasts demand.

Constructed from lightweight aluminum and finished in black anodized coating, the #3 Bulkhead Tee Fitting resists corrosion while maintaining a clean, professional appearance under the hood. The bulkhead design allows the fitting to be mounted through a panel or firewall with secure threading, eliminating the need for additional brackets or clamps in confined spaces. All three ports accept 3 AN male connections, providing uniform flow capacity and simplifying inventory management for builders working with standardized AN hose and adapter systems. The anodized aluminum construction keeps weight to a minimum—just 0.03 lbs—while delivering the structural integrity required for fuel pressure, coolant circulation, and pneumatic boost control applications.

This fitting is ideal for custom engine builders, race car fabricators, and serious DIY enthusiasts who demand OEM-grade reliability in their fuel, coolant, and boost systems. Installation is straightforward: simply thread the bulkhead body through a prepared panel opening and secure with the integrated mounting flange, then connect your 3 AN hoses or adapters to each port. The black anodized finish complements modern engine bays and resists the thermal cycling and vibration common in performance applications. Verify that your system's working pressures and fluid types are compatible with aluminum construction before installation to ensure optimal longevity and safety.
