ResMed VPAP Adapt SV Proximal Cuff

Quick answer: This is the genuine ResMed proximal cuff for the VPAP Adapt SV machine (part 26931). It’s a small connector that fits into the air tubing near the mask end — the pressure sensor tube attaches to it via a Luer connector so the device can measure pressure at the mask. It’s part of the Adapt SV air delivery system, and a cracked, lost, or worn cuff can lead to incorrect pressure readings or alarms. A simple replacement part for the legacy VPAP Adapt SV.

What’s included

• 1 × ResMed VPAP Adapt SV proximal cuff (part 26931)

Not included: air tubing, pressure sensor tube, tube clips — available separately, or as part of the complete air delivery system (PN 26923).

About this part

The VPAP Adapt SV measures pressure at the patient end of the circuit rather than only at the device. To do this, the proximal cuff sits in the air tubing near the mask, and the pressure sensor tube connects to it — the two join at the cuff with Luer connectors. This lets the device read mask pressure accurately and adjust therapy accordingly. The cuff is one component of the Adapt SV air delivery system, which also includes the air hose, sensor line, and tube clips. If the cuff is damaged or missing, or the sensor tube can’t seat properly, the device may report incorrect pressure or trigger alarms — so a genuine replacement restores correct operation without having to replace the entire tubing set.

Key features

• Genuine ResMed proximal cuff (26931) — correct fit for the VPAP Adapt SV.
• Luer connection for the sensor tube — secure, proper attachment.
• Enables mask-level pressure sensing — supports accurate pressure readings.
• Part of the Adapt SV air delivery system — with hose, sensor line, and clips.
• Simple, low-cost replacement — no need to replace the full tubing set.

Specifications

Setup & care notes

The pressure sensor tube and the air tubing join at the proximal cuff — make sure the connection is secure and that the sensor tube is not kinked, obstructed, or twisted, as this affects pressure readings. When cleaning, remove the pressure sensor tube and proximal cuff from the air tubing, then follow the cleaning instructions in the VPAP Adapt SV user guide. Inspect the cuff periodically and replace it if it’s cracked or no longer holds the sensor tube securely.

Is it compatible with my setup?

This cuff is designed for the ResMed VPAP Adapt SV. It is not intended for the S9 series or newer ResMed platforms, which use different tubing and sensing systems. If you’re unsure which parts your machine uses, contact us and we’ll help you identify the right components.

Frequently asked questions

What does the proximal cuff actually do?
It sits in the air tubing near the mask and provides the connection point for the pressure sensor tube, so the device can measure pressure at the mask rather than only at the machine.

Which device does it fit?
The ResMed VPAP Adapt SV. It is not intended for the S9 series or newer platforms.

What’s included?
The proximal cuff only (part 26931). Tubing, sensor line, and clips are not included.

Can I buy the whole tubing set instead?
Yes — the complete Adapt SV air delivery system (hose, sensor line, clips, and cuff) is available as PN 26923. Contact us if you’d like the full set.

When should I replace it?
If it’s cracked, worn, lost, or no longer holds the sensor tube securely — or if pressure-reading issues trace back to this connection.

Do I need a prescription?
Small replacement parts like this generally do not require a prescription. Contact us if you’re unsure.

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.

Use this part with your ResMed VPAP Adapt SV according to the device’s user guide. After fitting, ensure the pressure sensor tube is not kinked, obstructed, or twisted.
