Philips Respironics SST Flap for ComfortGel and ComfortGel Blue Nasal CPAP Masks

This is the replacement silicone flap that fits over the gel cushion on the ComfortGel and ComfortGel Blue Nasal CPAP Masks. Use the separate silicone membrane that snaps on over the gel cushion to increase the life of the cushion. The unique Sure Seal Technology (SST) contours and seals around the ComfortGel cushion.
