Abstract
Convoluted boot seals for use on universal joints operating at relatively large angles with the side walls of some convolutions having a series of contact ribs which are formed thereon where abrasion might cause seal wear and failure. These ribs are flexible so that they can bend over when they contact an adjacent, relatively turning side wall so that direct sliding contact and resulting abrasion between adjacent side walls are eliminated.
