In short

A fresh, leak-free outlet for your Rove 4

The RP-412 is the genuine Inogen Rove 4 cannula barb — and on the Rove 4 the output filter is built into the barb itself, so this single part is both the outlet connector for your nasal cannula and the output filter. This differs from older Inogen models, where the output filter is a separate piece. Fits the Rove 4 only; the Rove 6 uses its own barb (RP-506).

On the Rove 4, the cannula barb and the output filter are a single part. Over time the barb can wear, loosen, or crack from frequent cannula changes — a fresh one restores a firm connection and clean, filtered flow at the oxygen outlet.

Genuine Inogen part

Made to Inogen's Rove 4 outlet spec for the same fit and durability as factory.

Details

What's included

One genuine Inogen Rove 4 cannula barb with integrated output filter. On the Rove 4, the barb and output filter are a single part — unlike older Inogen models, where the output filter is separate. Cannula tubing is not included.

Why genuine matters

The genuine kit matches the Rove 4 outlet so the barb seats firmly and the filter seals the channel. An off-spec part can loosen, leak, or fail to seat the filter correctly.

Frequently asked questions

Do I need a separate output filter?

No. On the Rove 4, the output filter is built into the barb, so the RP-412 covers both. Older Inogen models (like the G4 and G5) use a separate output filter (RP-410).

When should I replace it?

Replace it when the cannula connection feels loose or unstable, or when you see wear or cracking on the barb.

Does it fit other Inogen models?

No. This part is designed for the Inogen Rove 4 only. The Rove 6 uses its own barb (RP-506).

Is it hard to install?

No. It's a simple press-fit replacement that most users can do at home in a few minutes.
