A sealing pad (100) for sealing a respiratory mask. The mask is configured to create a sealing interface. The sealing interface encircles the nostrils and includes portions crossing the nasal ridge and the concave portions. The pad has a face-contacting side to sealingly engage the face, and a mask contacting side to sealingly engage the mask. The pad (100) includes a portion for crossing the nasal ridge and portions (113) for crossing concave portions on either side of the nose such that the mask contacting side is engageable with the mask to define the portions of the sealing interface crossing the nasal ridge and the concave portions. The pad carries, or has one or more defined apertures (107) for carrying, one or more tube portions for conveying fluid across the sealing interface.
