Vibrant -4AN Bulkhead Nut - Aluminum

This is the Vibrant -4AN bulkhead nut, a key piece for custom fuel or oil line setups. It's designed to work with Vibrant's bulkhead adapters, allowing you to pass a -4AN hose connection through a panel or firewall securely. You get the nut itself, which is made from lightweight 6061 aluminum alloy and finished in black anodize for a clean look and some corrosion resistance.

When you're building a custom line, getting a solid, leak-free connection is critical, especially with fuel or oil. This nut, combined with the corresponding bulkhead adapter, helps create that secure pass-through. The 6061 aluminum construction means it won't add much weight to your setup, which is always a plus in custom builds. It's designed to provide a reliable seal, making assembly easier and giving you peace of mind.
