When you're building or modifying fuel or oil lines, sometimes you need to adapt one fitting size to another. This expander fitting from Fragola lets you connect a -4AN hose end to a -6AN male flare port.

This fitting is made from aluminum and has a black finish, which helps with corrosion resistance and looks clean in your engine bay. The threads are machined to ensure a good seal when properly tightened. It's a simple part, but getting the right adapter makes a big difference in the success of your custom line work.
