Moroso Universal Filler Cap Kit - 1-1/4-12UNF - Steel Bung - Black Anodized

This Moroso filler cap kit comes with a 1-1/4-12UNF threaded bung, which is a common size for many custom cooling system setups. The bung itself is made from steel, giving you a solid mounting point that's ready for welding into your radiator, overflow tank, or custom reservoir. The cap features a black anodized finish, which not only looks sharp but also helps protect the aluminum cap from corrosion.

When you're building a custom cooling system, having the right fittings is key. This kit gives you a well-built cap and a steel bung that you can integrate into your system wherever you need it. The 1-1/4-12UNF thread size is important to note, so make sure it matches the opening you plan to weld this onto. The black anodized finish on the cap adds a nice touch and helps keep it looking good over time.
