The Nova Nasal Mask Frame System connects the mask cushion and headgear to one another at one end and attaches to your CPAP machine at the other. Fisher & Paykel offers the frame system as a replacement part that you can buy separately from the other components to make it easier and more affordable to swap out CPAP mask pieces as needed. 

This replacement system includes the frame, tube, swivel, and diffuser. It comes as one piece, so it’s easy to swap in and out without significant assembly.
