About this part

Product Details

This is a Vibrant -8AN male to 1/4 inch NPT male union adapter fitting that also includes a 1/8 inch NPT port. It’s designed to connect components that use different thread types, like hooking up an AN hose to a component with NPT threads, while also giving you an extra port for a sensor or gauge. This fitting is commonly used in custom fuel systems, oil lines, or vacuum setups where you need to adapt between AN and NPT fittings.

Crafted from 6061 aluminum alloy, this adapter is lightweight and anodized black for a clean look. The aluminum construction helps keep overall system weight down, which is always a plus in performance applications. It’s built to provide a smooth flow and a reliable, leak-free seal when properly assembled, making it a solid choice for connecting popular oil pumps, fuel pumps, fuel filters, and other common engine components.

Remember that the 1/8 inch NPT port is open, so you'll need a port plug if you don't plan on using it for a sensor or fitting. This adapter comes with a one-year limited warranty from Vibrant.
