This is the replacement SST silicone flap that fits over the gel cushion on the ComfortGel Full Face Mask.
There are three (3) different Frame sizes for the ComfortGel Full Face Mask. Only use the cushion/flap that fits onto the your frame size. Frame, cushion and SST Flap sizes are not interchangeable.
- Large frame = Large cushion and flap
- Medium frame = Medium cushion and flap
- Small frame = Small cushion and flap
The same size silicone flap must be used to secure the gel cushion to the frame. The silicone flap and gel cushion are sold as a package elsewhere on our site, and the gel cushion is sold separately as well.
