Abstract
A captivated seal assembly is disclosed. The seal assembly may include a metal seat shield, an annular elastomeric seal and a metal bonding ring. The metal bonding ring is preferably bonded to and fully encapsulated within the annular elastomeric seal. The composite metal bonding ring and elastomeric seal is contained in an annular recess formed in the metal seat shield. The metal bonding ring is secured to the metal seat shield, thereby retaining the elastomeric seal within the annular recess of the metal seat shield. The metal bonding ring may include a plurality of support pads for engagement with an annular back wall of the metal seat shield.
