Description
Quick answer: This is the genuine ResMed replacement end cap for the Mirage Swift II nasal pillow mask (part 60525). The Swift II lets you connect the short tube on either the left or the right side — and the cap seals the side you’re not using. Without it, pressurised air escapes from the open port, which shows up as pressure loss, whistling, or a mask that simply won’t hold its seal.
What’s included
- 1 × Mirage Swift II end cap (part 60525)
Mask, pillows, short tube assembly, and headgear not included.
About this part
One of the nice things about the Mirage Swift II is that the short tube can attach on whichever side suits your sleeping position — and you can swap it over whenever you like. The end cap is what makes that work: it seals the unused port so all the airflow goes where it should.
It’s also one of the easiest parts to lose. It’s small, it’s removed whenever you switch sides or clean the mask, and it’s blue precisely so it’s easier to spot. When it goes missing, 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.

Frequently asked questions
What does the end cap do?
It seals the port on the side where the short tube isn’t connected, so pressurised air doesn’t escape.
Why does the mask have two ports?
So you can route the tube on the left or the right, depending on how you sleep. The unused side gets capped.
My mask whistles or feels weaker — could this be why?
Yes — a missing or loose end cap is a common and easily overlooked cause of pressure loss and whistling.
Which mask does it fit?

Do I need a prescription?

Can I get it delivered in Brooklyn or shipped nationwide?

Use this part with your ResMed Mirage Swift II mask according to the mask’s user guide. Keep the unused port capped during therapy.
