  • Elastomer seal
    Patent number: 5234221
    Abstract: An elastomer seal is described which is useful for forming a sealed, flat mounting surface on a curved housing. The elastomer seal has a flat sealing face opposite a curved sealing surface. An angled transition surface is adjacent to the curved sealing surface forming a bevel. The bevel assists the seal in properly deforming so that a sealing area is formed across the curved housing. This seal provides peripheral and central contact so that the distribution of compressed seal material is well spread over the surface of the sealed area. The elastomer seal is able to effectively seal housings with radii of curvature from 1 to 6.4 times the curvature radius of the curved sealing surface.
