Pro-werks Weld Plumbing Bungs are available in weld-able 6061-T6 Aluminum or Mild Steel, produced on machining centers responsible for so many of our precision parts. Available in both Male and Female versions.
The Pro-werks Male weld bungs feature a contoured inlet for maximum flow - precision CNC machined and available in your choice of 6061-T6 Aluminum or Mild steel.
You will appreciate the stepped shoulder at the base of the bung, it serves as a positioning locator. This design feature holds the bung in place while welding in a hole of a flat surface, or in the end of tubing. Ample cross section in the weld land also helps to reduce warping during welding.
