Bulkhead Adapter 90 Degr ee Elbow Fitting -3AN

The Bulkhead Adapter 90 Degree Elbow Fitting -3AN by Vibrant Performance is an essential hydraulic and fuel line component for serious automotive builders and engine enthusiasts working with custom cooling systems, fuel delivery upgrades, or remote-mounted coolers. This fitting solves a critical problem in tight engine bays where straight connections won't work: it allows you to route -3AN hose at a perfect 90-degree angle while maintaining a secure, leak-free seal. Whether you're upgrading a turbo cooler setup, installing a remote oil cooler, or fabricating a custom fuel system, this adapter bridges the gap between inline hose runs and perpendicular mounting surfaces.

Vibrant Performance engineered this bulkhead elbow with precision aluminum construction to handle the demanding pressures of modern engine modifications while resisting corrosion and thermal stress. The -3AN designation refers to the hose size (3/16-inch ID tubing), which is the industry standard for small-displacement cooling and fuel circuits where flow capacity and compact routing are equally important. The 90-degree angle eliminates the need for multiple fittings or custom bends, reducing potential leak points and simplifying installation in congested engine compartments. Vibrant's tight tolerances ensure a consistent seal that won't weep under boost or high sustained RPM, critical for protecting your engine investment from catastrophic fluid loss.

This adapter is ideal for turbo and supercharger enthusiasts installing intercooler piping, LS swap builders routing custom coolant or fuel lines around tight block geometry, and drift or road-race competitors who demand reliability under extreme operating conditions. The compact 1.5 x 0.75-inch profile fits cleanly in tight spaces where standard 45-degree or 180-degree fittings create packaging conflicts. Installation requires only a wrench and basic hose crimping knowledge—thread the AN hose onto the fitting's barbed end using a proper crimp tool, then bolt or clamp the bulkhead connection to your mounting surface. Compatible with any -3AN hose rated for your system's pressure and temperature, this Vibrant Performance fitting is a no-compromise solution for custom fuel, coolant, and oil line routing on street, strip, and track builds.
