Inogen One G4 Cannula Barb

The Inogen One G4 Cannula Barb is a small, lightweight accessory that attaches to the cannula tubing of your Inogen One G4 oxygen concentrator. This barb allows you to easily connect and disconnect your cannula tubing from the concentrator unit, so you can quickly and easily take your oxygen therapy on the go.

In order to change the Cannula Barb, the Output Filter Kit (RP-404) is needed.
