Weld in Fill or Drain Plug


A Universal Weld-in drain or fill plug. This is a 2-piece bung that can be welded into anything you like. It uses standard 3/4" NPT threads making it easily adaptable to common pipe fittings. These are the same fittings found on our diff covers.

The outside of the plug measures just over 1-1/4", a 1-3/8" hole is perfect for fitting in and having a solid weld. The hex wrench needed for the plug is 9/16".

The possibilities are endless:

  • Add a drain plug to any diff cover.
  • Add a fitting to an air tank.
  • Add a drain to a tubbed bed.
  • Extra fill or drain plug on a water tank.
