High-Flow Bungs


Contoured inlet for maximum flow


These 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.

Available individually, or bulk form in conveniently packaged bags of 20 for volume users.

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