The SST Flap for ComfortGel and ComfortGel Blue Nasal CPAP Masks is a replacement silicone comfort flap with an integrated retaining ring. This component fits over the gel cushion and locks it securely into the mask faceplate, providing the structural support needed for a reliable seal during CPAP or bi-level therapy.
Over time, the silicone flap can develop wear, cracking, or loss of flexibility, which may lead to air leaks and reduced therapy effectiveness. Replacing the SST flap restores the secure fit between the gel cushion and the faceplate, helping maintain consistent seal performance without replacing the entire mask assembly.
The SST flap is available in four sizes: Petite/Extra Small, Small, Medium, and Large. It is important to match the flap size to your existing gel cushion and mask frame size, as the cushion, frame, and flap must all be the same size for a proper fit. The size is printed or embossed on the bottom of the flap for easy identification.
This product is the silicone flap only and does not include the gel cushion. ComfortGel and ComfortGel Blue mask frames and cushions are interchangeable, but all components must be the same size. The flap is compatible with both the original ComfortGel and the ComfortGel Blue Nasal CPAP Mask systems.
This product is the silicone flap only. The gel cushion, mask frame, headgear, elbow, and tubing are sold separately.
Silicone Seal Construction: Made from durable silicone that fits over the gel cushion, the SST flap creates a smooth, comfortable surface against the face while securing the cushion to the faceplate.
Integrated Retaining Ring: The flap includes a built-in retaining ring that clicks securely into the mask faceplate, holding the gel cushion firmly in place throughout the night.
Cross-Compatible Design: Works with both the original ComfortGel and the ComfortGel Blue Nasal CPAP Masks, giving you flexibility across both mask systems as long as all components match in size.
Four Size Options: Available in Petite/Extra Small, Small, Medium, and Large with a size indicator printed on the flap for easy identification and proper matching to your cushion and frame.
Easy Replacement: The flap snaps on and off the faceplate without tools. Simply unhook the retaining ring clips, remove the old flap, and press the new one into place until it clicks.

The SST flap, gel cushion, and mask frame must all be the same size for a proper fit. Mixing sizes will result in a poor seal and may compromise therapy effectiveness.
The size of the flap is printed or embossed on the bottom of the SST flap. For example, an “L” on the bottom indicates Large. The sizing indicator may vary in color between batches, but this does not affect performance.
When using this mask with a Philips Respironics PR System One CPAP machine, use Resistance Control number X1. This value should be set by your provider to ensure optimal pressure compensation with Flex Technology.
A worn or cracked silicone flap can cause air leaks that compromise therapy. Replacing the SST flap restores the secure connection between cushion and faceplate for a reliable seal.
The SST flap is compatible with both the original ComfortGel and ComfortGel Blue Nasal CPAP Masks, so you can use the same replacement part regardless of which version you own.
The integrated retaining ring clicks directly into the faceplate without any tools. Remove the old flap, position the new one, press until it clicks, and you are ready for therapy.
The SST Flap is a silicone comfort flap with an integrated retaining ring that fits over the gel cushion on the ComfortGel and ComfortGel Blue Nasal CPAP Masks. It holds the gel cushion securely against the mask faceplate and provides a smooth silicone surface that contacts your face, helping create and maintain a proper seal during therapy.
No. The SST Flap is the silicone seal only. The gel cushion is a separate component and must be purchased separately if it also needs replacement.
The SST Flap is available in four sizes: Petite/Extra Small (1009052), Small (1009053), Medium (1009054), and Large (1009109). The flap must match the size of your gel cushion and mask frame for a proper fit.
The size is printed or embossed on the bottom of your current SST flap. Look for a letter such as L for Large, M for Medium, S for Small, or P for Petite. You can also use the ComfortGel printable sizing gauge to determine your size based on your facial measurements. The flap, cushion, and frame must all be the same size.
Yes. The SST Flap works with both the original Philips Respironics ComfortGel Nasal Mask and the ComfortGel Blue Nasal Mask. The frames and cushions for both masks are interchangeable, as long as all components are the same size.
To remove the old flap, lift up under the base on each side of the integrated retaining ring to unhook it from the faceplate. To install the new flap, place the gel cushion into the faceplate with the nose notch at the top, position the new flap over the cushion with the size indicator at the bottom, then slide it downward and press firmly until all three sides click into place.
Replace the SST Flap when you notice signs of wear such as cracking, tearing, hardening, or loss of flexibility. A worn flap can cause air leaks and reduce seal effectiveness. Inspect the flap regularly as part of your mask maintenance routine.
Hand wash the flap daily in warm water with a mild liquid dish washing detergent. Rinse thoroughly with clean water and air dry out of direct sunlight. Do not use bleach, alcohol, or cleaning solutions containing conditioners or moisturizers, as these can damage the silicone material.
The Resistance Control value for the ComfortGel and ComfortGel Blue masks is X1. This setting should be programmed into your Philips Respironics PR System One CPAP machine by your provider to ensure optimal pressure compensation when using Flex Technology.
No. The sizing indicator printed or embossed on the SST flap may vary in color between production batches, but this cosmetic variation does not impact the performance or function of the flap.
