Quick answer: This is the genuine ResMed complete anti-asphyxia valve (elbow) assembly (part 16613) for the Ultra Mirage Full Face mask — the whole valve unit that provides the mask’s safety valve and its tubing connection. It includes the elbow retainer, valve frame, valve membrane, valve elbow, swivel clip, and swivel — everything needed to replace the anti-asphyxia valve as a full assembly. The anti-asphyxia valve (AAV) admits room air if airflow stops, so you don’t rebreathe CO₂ inside a full face mask. Also fits the Mirage Series 2 and Mirage Full Face masks. No prescription required.
Important — anti-asphyxia valve (safety)
This assembly contains the anti-asphyxia valve (AAV) — a safety feature that opens to admit room air if airflow stops (machine off, unplugged, or failed), so you don’t rebreathe exhaled CO₂ inside a full face mask. During therapy, pressurized air holds the valve membrane closed. Make sure the valve and membrane are intact and working, and don’t use the mask with a damaged or missing valve. Keep the vent clear.
What’s included
- 1 × complete anti-asphyxia valve (elbow) assembly — including: elbow retainer, valve frame, valve membrane, valve elbow, swivel clip, and swivel (part 16613)
Mask, frame, cushion, and headgear not included.
About this part — and how it differs from 16624 / 16617
The anti-asphyxia valve assembly is the tubing connection and the safety valve for the Ultra Mirage Full Face mask, in one complete unit:
- Complete assembly (16613, this) — the whole valve unit: elbow retainer, valve frame, valve membrane, valve elbow, swivel clip, and swivel. Choose this to replace the entire valve/elbow assembly.
- Valve elbow (16624) — the elbow + swivel + membrane (a subset — no separate frame/retainer/clip).
- Valve membrane only (16617 / 16618) — just the small silicone membrane (1-pack / 10-pack); choose this if only the membrane is damaged.
Order 16613 for the full assembly; 16624 or 16617 if you only need part of it.

What’s included?

16613 is the complete assembly (whole valve unit). 16624 is the valve elbow (elbow + swivel + membrane). 16617/16618 is the valve membrane only (1-pack/10-pack). Order by how much you need to replace.
