Moroso Aluminum Fitting Adapter 6AN Female to 3/8in Tube Compression - Black

When you're building or modifying a fuel system, oil cooler lines, or any other fluid transfer setup, you often need to adapt different types of fittings. This Moroso adapter is designed to help you connect a 6AN female fitting to a 3/8-inch diameter tube using a reliable compression seal.

It's made from aluminum, which keeps the weight down and helps prevent corrosion in your fluid lines. The black finish gives it a clean look, and the compression fitting means you get a solid, leak-resistant connection without needing special tools like flaring equipment. This is a common piece you'll reach for when piecing together custom plumbing for your engine bay.
