Cap Assembly with Aluminum Weld-In Bung

This assembly includes a weldable aluminum bung. A convenient stepped shoulder is machined in the base of the bung, acting as a positioning locator during fabrication. This bonus feature holds the bung in place while welding in a hole on a flat surface, or in the end of tubing when building a filler neck extension. This is a great anti-frustration feature that is appreciated by the finish installer.

The lightweight, non-vented cap features positive grip finger notches that is easy to get a hold of. The 6061-T6 billet aluminum cap is CNC machined for accuracy with a lightweight, attractive design and features quick-starting coarse threads. Each is standard with a special positive sealing "radial squeeze" Buna O-ring, which also holds the cap secure. Billet Aluminum Fill Caps is a Pro-werks specialty.

Easy Turn Fill Caps are available in variety of sizes to fit most any application, big or small. To compliment the color coordination of your project, the caps are finished off in Pro-Werks Brilliance anodized colors in your choice of black, red, blue, silver, or beautifully Micro-polished aluminum. 

Proudly made in the USA.
