Moroso 1-1/4 -12UNF Aluminum Fill Cap Kit

This kit includes a Moroso 1-1/4 -12UNF aluminum fill cap. It's designed to replace your vehicle's standard radiator or expansion tank cap with a more durable and visually appealing option.

Crafted from aluminum, this cap offers a solid feel and resists corrosion better than many stock plastic caps. The 1-1/4 -12UNF thread size ensures it fits specific applications where this thread pattern is required, often found on custom cooling systems or certain performance radiators. It's a straightforward component that adds a touch of custom flair while providing a reliable seal for your cooling system.
