This simple add on will make purging a single O2 bung quick and easy! The side vents direct the gas RIGHT where you need it most, around the bung!
No more waiting for your entire tube to purge if you forgot to add in a bung!
When attached to our M18/O2 Bung heatsink it places the diffuser holes right below the surface smothering the weld bead in fresh argon.
