Silicone Nasal Seal for Forma, FlexiFit 431 & FlexiFit 432 CPAP Masks

  •  $18.95

We offer free shipping on every order over $99 so you can get what you need and save money too! (US & US Territories)

This clear (white) Silicone Seal is designed for use with all Forma (40047X), FlexiFit 431 (HC431) and FlexiFit 432 (HC432) Full Face CPAP and BiPAP Masks.

COMPATIBILITY: The FlexiFit 431 uses only the Silicone Seal while the Forma and FlexiFit 432 masks use both a Foam Cushion and Silicone Seal. If you are using a Forma or FlexiFit 432 mask and would like to purchase a cushion and seal set, those can be found elsewhere on this site.

SIZING: 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.

I have a cpap and my insurance doesn't pay anything on it. These prices are great and the quality is exceptional.

Best Comfort and Fit
Written By: Pat K, CA 9/15/2013
The mask is shaped to tuck comfortably "under" the chin, without putting pressure on my lower teeth. It is much lighter in weight than other full face masks I have tried. The nose bridge fits better and without skin irritation. This is the best mask I have tried, and the most comfortable. Would highly recommend it to others.
