Fill Cap Bungs


Pro-werks Fill Cap Bungs are available separately without the cap. This selection of weld-able bungs includes several different heights; available in Steel, Aluminum or Stainless steel materials.

Properly sized  for the "radially squeezed" O-ring standard of the signature Pro-werks Easy Turn Fill Cap.

Note: Welding should always be performed by a qualified welder.

The bolt-on style bung selection is also available, and does not require welding. Select anodized colors are available and also include mounting hardware - so you won't need to run all over town looking for it!


Great caps. Great colors.



These bungs utilize the popular non-vented Easy Turn Fill Caps that are available variety of Pro-Werks Brilliance anodized colors or beautifully Micro-polished aluminum finish - the finishes are impeccable.


The right size matters.
