Fisher & Paykel: 400HC112, 400HC104, 400HC103

This clear (white) 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.

  • Flexfit 431

    I am not happy with the product, It doesn't fit tightly -therefore it is noisy, don't know what you can do but am not using it
