摘要

A plug assembly for sealing an opening formed to access an internal gallery inside a subsea component is described. The plug assembly comprises a threaded body and a sealing body. The threaded body comprises a top surface; a bottom surface; a threaded portion for engaging with the walls of the opening between the top and bottom surface; and a head connected to the top surface for engaging with a tool for screwing the plug assembly into the opening; The sealing body comprises a cylindrical section having a flange extending from the top of the cylindrical section; and a frusta-conical section extending from the base of the cylindrical section and having an recess extending within the base of the frusto-conical section. The cylindrical section comprises an annular groove for receiving at least one sealing member; and the frusto-conical section has a first taper section and a second taper section, wherein the first taper section defines an undercut between the cylindrical section and the second taper section.
