Male Bulkhead Union Fitt ing; Size: -3 AN

The Vibrant Performance Male Bulkhead Union Fitting in -3 AN size is a straight-through adapter designed for high-pressure fluid systems where two male AN connections must pass through a panel, bulkhead, or firewall. This aluminum fitting with black anodized finish serves as an intermediate coupler in hydraulic and fuel line applications, allowing reliable sealed connections on both sides of a structural barrier without requiring internal space behind the bulkhead.

The -3 AN designation indicates a nominal line size of 3/16-inch, accommodating 3 AN male ports on both the inlet and outlet sides. Aluminum construction provides weight savings critical in racing, aerospace, and marine applications, while the black anodized surface offers corrosion resistance and professional appearance. The bulkhead union design eliminates the need for separate washers or sealing compounds when installed properly, simplifying assembly and reducing leak points in pressurized systems. Compact dimensions (3.15 x 0.95 x 3.85 inches) ensure fit in tight engine bays and confined compartments common in custom builds and high-performance vehicles.

This fitting is essential for builders integrating fuel injection systems, turbo oil lines, transmission coolers, and custom hydraulic setups where panel penetration is required. Professional mechanics and fabricators rely on Vibrant Performance fittings for consistency and durability under sustained pressure. The straight configuration maintains flow characteristics without the restriction or directional limitations of elbows or tees, making it ideal as a panel-mounted junction point in organized line routing. Whether outfitting a project car, off-road truck, or marine engine system, this bulkhead union provides a proven, leak-resistant connection standard throughout the automotive aftermarket.
