Vibrant -4AN Male to 1/4in Tube Adapter Fitting (w/ Brass Olive Insert)

This Vibrant adapter fitting starts with a 1/4 inch tube OD size, designed to connect directly to your hardlines. It's made from 6061 aluminum alloy, which keeps the overall weight down while still offering solid durability for your fuel or oil system. The black anodized finish helps protect the aluminum from corrosion and gives it a clean look in your engine bay.

What makes this fitting particularly useful is the included brass olive insert. This insert creates a reliable seal when you crimp it onto your 1/4 inch tube, ensuring a leak-free connection as you transition to the -4AN male thread. This setup is a common way to adapt factory hardlines to aftermarket AN-style hoses and components, making fabrication projects more straightforward.
