ResMed Mirage Quattro / Quattro FX Elbow Assembly

Description

Quick answer: This is the genuine ResMed elbow assembly for the Mirage Quattro and Quattro FX full face masks (part 61294) — a complete replacement that includes the elbow, swivel, anti-asphyxia valve (AAV), and clip. It restores the mask’s 360° tangle-free rotation and, importantly, its built-in anti-asphyxia safety valve (which admits room air if airflow stops). Replace the whole assembly when the plastic cracks, the swivel binds, or the valve wears. Fits Mirage Quattro, Quattro FX, and Quattro FX for Her — not the Quattro Air. Mask, cushion, and headgear not included.

What’s included

• 1 × elbow
• 1 × swivel
• 1 × anti-asphyxia valve (AAV)
• 1 × clip

(Complete elbow assembly, part 61294.) Mask frame, cushion, and headgear not included.

About this part

The elbow assembly is where the tubing meets the mask — and on the Mirage Quattro / Quattro FX it does two jobs at once:

• 360° swivel connection — lets the hose rotate freely so you can move and change position without tube drag or breaking the seal, and detach the hose easily for bathroom trips or cleaning.
• Anti-asphyxia valve (AAV) — a safety feature: during therapy, pressurized air holds the valve closed; if airflow stops (machine off, unplugged, or fails), the valve opens automatically so you breathe room air instead of rebreathing exhaled CO₂ inside a full face mask.

Because this is the complete assembly, replacing it restores both the smooth rotation and the safety valve at once. Over time the plastic can crack, the swivel can loosen or bind, or the valve can stiffen or stop sealing — any of which is a reason to replace it. As it includes a safety component, don’t run the mask with a damaged or missing valve.

Compatibility — important: fits all Mirage Quattro, Quattro FX, and Quattro FX for Her full face masks. It is not compatible with the Quattro Air series (a different, newer mask). (Note: recent versions of this elbow have a solid ridged circle at the mask end rather than the older “crenelated” edge — both fit the same masks.)

Frequently asked questions

What’s included?
The complete elbow assembly — elbow, swivel, anti-asphyxia valve, and clip. The mask, cushion, and headgear are separate.

What does the anti-asphyxia valve do?
It’s a safety feature: if airflow stops (machine off/unplugged/fails), the valve opens so you breathe room air instead of rebreathing exhaled CO₂. Don’t use the mask with a damaged or missing valve.

Which masks does it fit?
The Mirage Quattro, Quattro FX, and Quattro FX for Her full face masks. It’s not for the Quattro Air series.

When should I replace it?
When the plastic cracks, the swivel loosens or binds, or the valve stiffens or stops sealing. Because it includes a safety valve, replace it promptly if the valve is worn.

My elbow looks a little different from the picture — is it the right part?
Recent versions have a solid ridged circle at the mask end instead of the older crenelated edge. Both are 61294 and fit the same masks.

Do I need a prescription?
No — this replacement part does not require a prescription.

Can I get it delivered in Brooklyn or shipped nationwide?
Yes — Stark Medical Supplies offers local pickup and delivery in Brooklyn and across NYC, plus USPS shipping throughout the continental U.S.

This assembly includes an anti-asphyxia safety valve. Use with a compatible ResMed Mirage Quattro / Quattro FX mask according to the mask’s user guide, and ensure the valve is intact and working before use.
