This is the replacement gel cushion and SST flap that fits on the ComfortGel and ComfortGel Blue Nasal Masks.

There are three (3) different Frame sizes for the ComfortGel. Only the sizes Small and Medium cushions fit onto the same frame. (see Important Tips for more additional help)

Customizable Gel Cushion. As an added benefit, the ComfortGel cushion can be boiled and molded for a custom fit. The boiling process softens the cushion and allows the gel to form around your unique face. For more information on the boiling process, click on the Customizing the ComfortGel Cushion Instructions.

Silicone Cushion Flap. Does your mask get worn and "mushy" too quickly? 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.

Material Components of Original Gel Cushion and SST Flap for ComfortGel Nasal CPAP Masks

• Gel Cushion: Urethane Gel

• Gel Cushion Outer Shell: Urethane Film

Replacing Mask Frames and Cushion with SST Flap

ComfortGel and ComfortGel Blue mask frames and cushions are interchangeable, but the cushion and frame must be the same size. ComfortGel Blue Cushion for ComfortGel Nasal CPAP Masks will work with either mask.

• Large frame = Large cushion and flap
• Small/Medium frame = Medium cushion and flap
• Small/Medium frame = Small cushion and flap
• Petite frame = Petite cushion and flap

The same size silicone flap must be used to secure the gel cushion to the frame.

Where do I find the size?

The size of the gel cushion and the SST flap is located on the bottom of the gel cushion, where the mask frame and nasal cushion connect. If the mask is a size small, medium, or large, the letter indicating the size of the mask will be black. If the cushion is petite, a blue letter will indicated the size of the cushion.

If the user removes the gel cushion from the SST 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.

System One Resistance Control

Resistance Control is a numbering system on all new Respironics CPAP masks and based on variable resistance characteristics. Each number instructs the device to compensate for different mask types. The result is a consistent and reliable pressure, enhanced with all the benefits of Flex Technology, no matter which mask is used.

You can find the Resistance Control number next to the size indicator on the SST FLap. The size of the frame, cushion, or flap is printed or embossed on each individual part. An example of the size indicator is a printed "L" meaning the replacement part is a size "Large." Use the number next to the Size for use with you PR System One CPAP Machine.
