Opus 360 Nasal Pillow Mask & Replacement Parts

The Fisher & Paykel Opus 360 is a nasal pillow CPAP mask built around a minimalist, under-the-nose design that keeps the field of vision clear and puts the least amount of material against your face. This collection carries the replacement components that keep an Opus 360 sealing well and feeling comfortable night after night — because it's the cushion and headgear, not the frame, that wear out first.

Two things tend to bring Opus 360 users here. The first is the seal. Nasal pillow silicone softens and loses its shape over months of use, and a mask that once sealed silently starts to leak. The Opus 360 Nasal Mask without Headgear (400HC526) replaces the nasal pillow cushion assembly on its own, so you can restore a fresh seal without buying a complete system. It's a single-patient-use component and comes in the nasal pillows style the Opus 360 is known for.

The second is the headgear. Straps stretch over time, and once they do, you find yourself overtightening to compensate — which causes marks, discomfort, and paradoxically more leaks. The Fisher & Paykel Headgear for Opus 360 (400HC310) in black is a direct replacement that returns the mask to a secure, even hold without the guesswork.

A common question: do these parts fit only the Opus 360? Yes — both are designed specifically for the Opus 360 frame, so they're not interchangeable with other Fisher & Paykel masks like the Brevida or Pilairo. If you're unsure which pillow size you need, check the size code printed on your current cushion before ordering. Most users replace the cushion every one to three months and the headgear every six, though your own wear will vary.
