Abstract
A seal assembly is adapted to provide a seal between a body member and an object, having a cylindrical outer surface, arranged to penetrate an opening provided through the body member. The seal assembly includes a lead ferrule having a frusto-conical first surface adapted to engage a body member circular shoulder edge, and having a frusto-conical second surface; an intermediate follower having one circular edge adapted to engage the lead ferrule second surface; a rear ferrule having a frusto-conical third surface adapted to engage another circular edge of the intermediate follower; and a compression cap adapted to exert a longitudinal force on the rear ferrule. When the compression cap is tightened, the seal assembly sequentially provides three longitudinally-spaced seal zones, and a seal between the body member and the object.
