Description
Quick answer: These are genuine ResMed replacement port caps for the Mirage Quattro full face mask, supplied as a 10-pack (part 61296). The Mirage Quattro elbow has a port (used for connections such as oximetry or pressure sampling); the port cap seals it when it’s not in use, so pressurised air doesn’t escape. A missing cap causes a leak — pressure loss, whistling, and a mask that won’t hold its seal. A 10-pack keeps spares of this small, easily-lost part on hand. Mask not included.

About this part
Full face masks like the Mirage Quattro include a port on the elbow — a small opening that can be used for connections such as pressure monitoring or supplemental oxygen. When nothing is connected, that port has to be sealed, and the port cap is what seals it.
It’s a tiny part with an outsized effect: if the cap is missing or not seated, pressurised air escapes straight out of the open port. The symptoms are easy to misread — a faint whistle, therapy that feels weaker than usual, or leak alerts that don’t improve however you adjust the headgear. Because the cap is small and removed whenever the port is used, it’s exactly the kind of thing that gets lost.
A 10-pack is the practical size for clinics, providers, or anyone who wants spares of a part that’s easy to misplace.
