Built-in features and extra height


There are many height choices listed here to meet your unique requirement. Certain heights are only offered by themselves, requiring the Pro-werks Easy Turn Fill Cap to be purchased additionally to build complete assembly.

You’ll appreciate the stepped shoulder in the base of the bung - it serves as a positioning locator during the fabrication process.

Precision machined of weld able 6061-T6 Aluminum with ample cross section to reduce warping from welding, and is sized correctly for the radial squeeze O-ring design of the Pro-werks Easy Turn Fill Cap.

Proudly made in the USA.
