Fill Cap Bungs

Pro-werks Bungs are available separately, without the cap. There are many types available in various sizes and heights. Where applicable, colors are available and the weld able versions are available in Steel, Aluminum or Stainless. All of the bolt-on style bungs also include the mounting hardware, so you won’t need to run all over town looking for it.

These feature the proper relief size for the radial squeeze O-ring design of the Pro-werks Easy Turn Fill Cap.

Proudly made in the USA.
