Renew the Sanitation, Seal & Comfort for the F & P HC406 with a New Cushion

Foam insert and silicone cushion replacement for the Fisher & Paykel HC406 mask. Over time you may experience general wear and tear on the cushion and seal of any CPAP mask, instead of being forced to purchase a new mask, you can easily and quickly replace the seal insert thanks to this replacement kit.

Key Features

  • Premium Frosted Silicone Seal - Soft, smooth feel slides on the face, while the frosted texture ensures a mask seal
  • Auto-Contouring Fit - Adjusts on the fly to a variety of nose and face, shapes and sizes, for simple fitting

    Reviewers Tip:

    Rather than purchasing a new mask, picking up the replacement seal allowed for continued use of a mask that I had grown to love. Over time seals may become less comfortable due to general wear and tear, but replacing a seal was effective and cheap compared to having to replace a whole mask.

    How to Assemble the Flexifit 406

    Reassembeling the FlexiFit 406 Nasal Mask is easy using these instructions.

    I am currently using the Fisher & Paykel FlexiFit 431, will this seal work?

    No, this seal is designed specifically for the HC406, however we do have replacement seals for the FlexiFit 431
