  • Double beaded spaghetti seal with stiffness increasing deformation behavior
    Patent number: 5551705
    Abstract: A spaghetti seal for use in a surface to be sealed to a confronting surface and having a pair of projecting beads for sealing against the confronting surface. The beads are molded to incline inwardly towards each other or when installed are caused to incline towards each other. Under load, the beads are forced in contact with each other in a controlled manner. When in contact they behave essentially as a single bead to provide increased stiffness and more effective sealing.
