Fragola -4AN Bulkhead Nut - Steel 7/16-20

When you're building a custom fuel or oil line setup, sometimes you need to pass a line through a firewall or a panel. This Fragola -4AN bulkhead nut is designed to help you do just that. It's made from steel, so it's strong enough for most automotive applications, and it features a 7/16-20 thread size, which is common for -4AN fittings.

The bulkhead design means it has a flange that sits on one side of the panel, while the nut threads onto the other side, creating a secure pass-through. This helps keep your lines organized and protected, especially when routing them through sheet metal. It's a simple but essential piece for any custom plumbing job where you need a clean and professional-looking transition.
