Abstract
A metal end cap seal for sealing against resent invention relates to seals within a fluid system. The metal end caps of the seal include protrusions or nibs on the terminal ends of the caps, providing for reduced friction during installation and use. The seal may also include a base elastomer and an insert elastomer, the base elastomer and insert elastomer having different material properties from one another. The insert elastomer is selected to reduce friction with a sealing surface.
