Abstract: A collapsible planar sealing gasket includes a number of longitudinally extending sections disposed in an end-to-end relationship with each longitudinal section being integrally and continuously joined to an adjacent longitudinally extending section by a corner portion that has an arcuate cut in the gasket material extending from one longitudinal section to an adjoining longitudinal section so as to define a rounded portion of gasket material which allows the bending of the gasket material between a collapsed and an operable position.
Abstract: A multi-piece gasket utilizes pieces of elongated gasket material that have ends terminating in a number of longitudinally extending fingers with grooves disposed therebetween. The mating of the fingers and grooves defines a gasket joint and a seam line having a length greater than twice the width of the joined gasket pieces.
