Vibrant -4AN Female Straight Union Adapter (AN to AN)

When you're building or modifying a fuel system, oil lines, or any other fluid transfer setup, you often need to connect different types of fittings. This Vibrant Performance straight union adapter is designed to help you bridge the gap between a -4AN female fitting and another -4AN female fitting. It's a simple, direct way to join two lines or adapt a component with a -4AN female port to accept a standard -4AN hose end.

This adapter is made from 6061 aluminum alloy, which keeps the weight down, a big plus when you're working on custom builds where every ounce counts. It's finished in black anodizing, which not only looks good but also helps protect the aluminum. The design focuses on a smooth flow path to avoid restricting your fluid lines and ensures a solid, leak-free connection when properly assembled. It's a popular choice for connecting to common components like fuel pumps, oil pumps, and fuel filters.
