Vibrant 1.5in OD Aluminum Weld Bungs w/ Black Anodized Threaded Cap (incl. O-Ring)

If you're fabricating a custom oil tank or catch can for your build, you'll need a clean way to add a fill port or access point. These weld bungs from Vibrant are designed for that exact purpose. They're made from 6061 aluminum, which is a popular choice for fabrication because it's easy to work with and lightweight.

The flange on this bung has an improved design that helps prevent it from warping when you're welding it into place. It comes with a threaded cap that's black anodized for a nice finish and includes an O-ring to seal it up tight. Just remember not to weld the bung with the cap installed, as that could damage the threads or the O-ring.
