This 3M Speedglas SG-30W breathing tube is a genuine replacement part for the Adflo and TR-300-SG powered air-purifying respirators (PAPRs) used with welding helmets.


The self-adjusting feature is nice – it moves with your head without pulling or resistance, so you can turn and look around comfortably while welding.
The quick-release swivel connection lets you attach or detach the tube with one hand, which is handy when you're geared up and don't want to fumble with clips.


Made in the USA, and the package includes the tube only – no filters or turbo unit.
