    Product Overview

    Manufactured by Philips Respironics.

    Product Features

    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.

    Important Tips

    Where do I find the size?

    To find the size of the gel cushion and the silicone flap, locate the bottom of the gel cushion, where the mask frame and full face cushion connect. The black letter printed on the bottom of the full face cushion designates the size of the full face cushion and silicone flap.

    If the user removes the gel cushion from the silicone flap, the size will not be identifiable. The size of the gel cushion is not recorded, yet it directly corresponds to the size written on the silicone flap.
