The sealing interface comprises a foam or gel inner cushion and a thin resilient rubber outer sheath. A face side of the inner cushion resiliently supports the outer sheath. In one embodiment the inner cushion has at least two holes through a perimeter wall adjacent the face side of the inner cushion so that portions of the face side of the inner cushion adjacent to the holes compress more easily than portions of the face side of the inner cushion located between adjacent hole. In another embodiment, the inner cushion has at least two cavities in the face side of the inner cushion, the cavities resulting in portions of the sealing interface that compress more easily compared to portions of the sealing interface at positions in between the cavities. 2616/21 101 109 107 6 107- 55 0 0 7107 0 140-- 0C FIGURE 13A 11 /101 109 -- 55 107 107 107 FIGURE 1.3B 56
