In short

A tight seal for your G4 outlet

The SP-711 is the genuine Inogen One G4 cannula barb — the small outlet nozzle that connects your nasal cannula to the device for a tight, leak-resistant seal. It is not a filter. You remove and reseat it whenever you change the output filter beneath it. G4-only.

A fresh, well-fitting barb holds your cannula securely so oxygen reaches you, not the room. Because the output filter sits right beneath it, keeping a spare makes monthly maintenance fast.

✅ Inogen One G4 ❌ Not for the G3, G5, or Rove 6

Shop the compatible concentrator: Inogen One G4

Secure, leak-resistant fit

Holds the cannula firmly and seals the output channel on the G4 outlet.

Quick DIY replacement

Press-fit by hand in minutes — you'll remove it anyway when changing the output filter.

Genuine Inogen part

Made to the G4 outlet spec so it seats smoothly without tools.

Details

What's included
One genuine Inogen One G4 cannula barb (SP-711) and a quick install tip card. Output filters (RP-410) and the RP-404 tool are sold separately.
Why genuine matters
The genuine G4 barb press-fits and holds the cannula firmly without pliers. A worn or off-spec barb can loosen, leak, or fail to seat the output filter correctly.

Frequently asked questions

Is the cannula barb a filter?
No. It is the outlet nozzle that connects your cannula to the device. The RP-410 output filter sits directly beneath it.
When should I replace it?
Replace it when it's cracked, loose, discolored, or won't hold a secure seal. Many users keep a spare for monthly output-filter changes.
Does it fit the G5 or Rove 6?
No. The SP-711 is for the G4 only. The G5 uses the RP-505 barb and the Rove 6 uses the RP-506.
