Abstract: A known gland 11 includes first and second members 12 and 13. Prior art seals 33 (FIGS. 1A and 1B), 40 (FIG. 2A and 2B) or 50 (FIG. 3) can be used to seal the gland 11. Also, a novel, double acting, over center cone, articulating compression seal 60 (FIGS. 4 and 5) can be used to seal the gland 11. The seal 60 includes a base 61, an articulating compression arm 62, and a rocker 63. The arm 62 is connected to the base 61 at one hinge region 73 and to the rocker 63 at another hinge region 83. The articulating compression arm 62 is cone shaped, and the cone inverts as the seal 60 is displaced from a relaxed position (FIG. 4) to a sealed position (FIG. 5). The rocker 63 extends radially and longitudinally in the relaxed position and extends longitudinally in the sealing position.
