System and method for installing a manifold plug

A plug configured to be installed with a tool having a male threaded device, the plug for sealing a hole in a device and comprising:

• a core having a height and a smooth outer wall that includes a smooth tapered section and a smooth cylindrical section, the core having a core hole extending at least partially therethrough and a bottom portion of the core is solid with a depth of the core hole being less than the height of the core, at least a portion of the core hole being threaded,
• a metallic sleeve having a smooth inner surface defining a cylindrical void and having a smooth outer surface, the core being connected to the metallic sleeve at a lower end of the metallic sleeve prior to retraction of the core into the sleeve;
• the plug configured to be inserted into the hole with the threaded portion of the core hole being accessible from outside the hole of the device;
• and
• the core is configured to be retracted in an axial direction towards the outside of the hole of the device such that both the smooth tapered and smooth cylindrical sections of the core are pulled into the smooth cylindrical void of the metallic sleeve whereby the outer wall of the core seals with the cylindrical void of the sleeve to retain the core within the sleeve and wherein the plug is configured such that when the plug is installed in the hole of the device such that the core is in a position retracted into the sleeve with the threaded hole facing outwards and such that the core exerts outward pressure on an inner surface of the metallic sleeve, first the tapered section of the core is retracted into the sleeve and seals the hole of the metallic sleeve and then the tapered section of the core is next retracted into the sleeve and also seals the hole of the metallic sleeve, with the threaded hole free from engagement with the male threaded device after installation of the insert in the hole of the device and removal of the male threaded device.
