Moroso Weld-In Fill Cap w/Neck/Bung & O-Ring

This is a weld-in fill cap assembly from Moroso, designed for custom cooling system fabrication. It includes a neck or bung that needs to be welded into your radiator or expansion tank, along with a properly sealing O-ring for the cap itself. This setup is useful when you need to add a fill point or modify an existing cooling system where a standard cap won't fit.

The cap features a durable O-ring to ensure a tight seal, which is important for maintaining proper system pressure and preventing coolant loss. The included bung provides a solid mounting point for welding into custom tanks or radiators, giving you a clean and secure way to integrate a fill cap into your build. It’s a well-built piece that gives you the flexibility to create a custom cooling setup that works for your specific application.
