FlexiFit 431 Seal and 432 Seal Replacement for the Fisher & Paykel FlexiFit 431 & 432
- Silicone seal for full face CPAP mask.
- Fits Fisher & Paykel FlexiFit HC431 & HC 432 full face mask
The clear Silicone Seal is designed for use with all Forma (40047X), FlexiFit 431 (HC431) and FlexiFit 432 (HC432) Full Face CPAP/BiPAP Masks. Please note that the FlexiFit 431 uses only the Silicone Seal while the Forma and FlexiFit 432 masks use both a Foam Cushion and Silicone Seal.
The FlexiFit 431, FlexiFit 432, and Forma each use a single frame for all sizes; therefore, if you would like to change the size of your mask, you just need to purchase a different seal (or cushion and seal) size.
