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.
