3MH70-0716-0685-2 - 3M Speedglas Self-Adjusting QRS Breathing Tube for 9100 FX Air

Freedom of Movement While You Weld

If you use a Speedglas Adflo system, you know that the air hose can sometimes be your worst enemy—getting caught on the corner of a welding table or dragging heavily when you lean forward. The 3M Speedglas 834016 Self-Adjusting Breathing Tube solves that problem. Think of it like a slinky for your air supply; it stretches out when you need the reach and snaps back to a compact size when you stand up straight. This keeps the hose tight against your back, preventing it from bowing out and snagging on everything in your shop.

Easy On, Easy Off

Nobody wants to fumble with complicated latches when they are ready for a lunch break or need to use the restroom. This tube comes with the QRS (Quick Release Swivel) connection. You can literally disconnect your helmet from the blower unit with one hand in a split second. The swivel action is a huge bonus too—it spins freely, so you don't feel the hose fighting you or twisting up when you turn your head or maneuver into an out-of-position weld. It just follows your movement naturally.

Built for the Daily Grind

This is the standard polyurethane tube that comes with most 9100 FX Air kits. It is lightweight and flexible, making it comfortable for all-day wear. While there is a heavy-duty rubber version available for extreme heat and spark environments, this self-adjusting model is the preferred choice for general fabrication because it is so much lighter and less intrusive. It helps reduce neck strain by not pulling down on the back of your helmet.

Keep Your Air Clean

Your lungs are your most important tool. A damaged hose means you might be breathing in the fumes you are trying to avoid. Check your tube regularly. If you see any cracks, holes, or deep scratches, swap it out immediately with this genuine replacement. It’s a small investment to keep your expensive PAPR system working correctly and keeping your lungs pink.
