3M™ Speedglas™ self-adjusting length breathing hose

The self-adjusting length breathing hose (52.5 to 85 cm) features a quick-disconnect swivel connector for the 3M Adflo forced-air system. 3M's new welding visors and face shields feature the QRS (Quick Disconnect Swivel Connector) breathing hose, which allows the hose to be connected and disconnected with one hand. The breathing hose can also be used on 3M Speedglas 9000 Series welding visors and 3M visors using the 53 35 06 adapter. The life of the breathing hose can be extended by either using a shield or using a reinforced rubber hose.
