<p>A kiss seal (42) of C-shaped cross section is provided. The kiss seal (42) includes a first leg (54), a second leg (56), and an arcuate middle portion (46) extending therebetween. The first leg (54) includes a contact surface (24') positioned adjacent a separable flange (28). The second leg (56) is attached to an opposed attachment flange (18) using a face plate (20') and a number of screws (22). The second leg (56) is generally located directly beneath the first leg (54). During sealing use, the arcuate middle portion (46) extends greater-than-180 degrees and is located outboard of one or both flange outboard edges (31). This provides a resultant force vector (58) that acts to enhance sealing. The greater the pressure (P) on the arcuate middle portion (46), the greater the force vector components available to promote sealing. <IMAGE></p> |
