Vibrant -10AN Female to -4AN Male Reducer Adapter

Vibrant Performance is known for making well-built fabrication components, and this reducer adapter is a great example. If you're putting together a custom fuel system, oil lines, or any other fluid transfer setup, you'll often run into situations where you need to connect two different AN fitting sizes. This adapter lets you step down from a -10AN female fitting to a -4AN male fitting, making it easy to connect components with different port sizes.

It's made from 6061 aluminum alloy, which keeps the weight down, and it's black anodized for a clean look and some added durability. The design focuses on smooth flow and a seal that's resistant to leaks, which is crucial when you're dealing with fuel or oil lines. You'll find these types of adapters are commonly used with popular oil pumps, fuel pumps, and fuel filters, or really any component that uses AN-style fittings.
