Abstract: A lightweight sealing structure is provided for pressure vessels wherein a resilient ring carrying two O-rings is positioned adjacent the closure and wall of the vessel. Internal pressure urges the resilient ring and O-rings into sealing engagement with the internal surface of the vessel.

Abstract: Tapered cavities are lined with a plastic liner such as a reducer filler flange by forcing a deformable plastic tube into the cavity to reduce the diameter of at least the portion of the tube which passes through the cavity and flanges are formed on the plastic tube.
