Abstract
A sealing system for an outlet of a plastic-lined cylinder has a plastic liner outlet extending into a bore of a boss. An insert is engageable with the bore, forming a primary seal between the insert and portion of the liner outlet. A tapered compression surface of the insert engages a tapered bore portion of the liner outlet adjacent the primary seal forming a tapered interface and a secondary seal. An axial position in the boss, and dimensional integrity, of the liner outlet is maintained by engaging an annular distal end of the liner outlet in the bore by a stop. The stop can be formed on the insert.
