Bulkhead Adapter Tee on Run Fitting; Size: -3AN

The Bulkhead Adapter Tee on Run Fitting in -3AN size is an essential fluid distribution component for any serious performance fuel system, coolant line, or turbo supply application. Designed by Vibrant Performance, this adapter serves as a junction point where a single incoming line splits into two outgoing runs, allowing mechanics and fabricators to route pressurized fluids to multiple destinations with precision. Whether you're building a custom fuel rail setup, integrating a secondary cooler circuit, or plumbing a turbo charging system, this tee fitting enables clean, leak-free connections that maintain system integrity under boost or high-flow conditions.

Constructed with tight tolerances and manufactured to Vibrant Performance's exacting standards, the bulkhead adapter tee features precision AN threading that guarantees reliable engagement without cross-threading or stripped connections—a critical requirement when dealing with pressurized systems. The -3AN designation indicates a 3/16-inch nominal line size, making it ideal for mid-range fuel delivery, coolant circulation, or oil cooling applications where flow volume demands more capacity than smaller -2AN fittings but doesn't require the bulk of -4AN lines. The tee configuration positions the branch outlet at a 90-degree angle to the run line, maximizing flow control and allowing you to isolate or meter flow to secondary components through individual valve or gauge connections.

This fitting is indispensable for EFI conversions, turbo system builds, and any fabrication where you need to split flow without relying on bulky manifolds or multiple separate unions. Experienced fabricators appreciate the compact footprint—at just 3.5 inches long and weighing only 0.05 pounds—which fits neatly into tight engine bay layouts without adding unnecessary mass. Compatibility with all standard -3AN hoses, fittings, and adapters means you can integrate this tee seamlessly into existing line sets, making it perfect for incremental system upgrades or complex cooling and fuel delivery architectures on both street and track vehicles.
