Fragola -4AN Nut x -3AN Male Swivel Reducer

When you're building a custom fuel system or need to adapt different AN fitting sizes, a reducer like this Fragola -4AN to -3AN male swivel fitting comes in handy. It's designed to bridge the gap between a -4AN hose end and a -3AN male port, ensuring a secure and leak-free connection for your fuel or oil lines.

This fitting is made from aluminum, which keeps the weight down while still offering good durability for most automotive applications. The swivel feature on the male end means you can orient it perfectly after tightening the nut, making installation easier and preventing any kinks or stress on your hose. It's a straightforward part, but getting the right adapter saves a lot of headaches when you're piecing together your custom setup.
