Abstract: A plug for protecting the interior of a recessed area of a component during storage is disclosed herein. The plug includes a lubrication fitting positioned thereon to flow a protective material, such as grease, into the cavity between the lower end of the plug and the recessed area and any remaining voids between the walls of the plug and the walls of the recessed area. The plug may also include an engagement surface to assist in the insertion and removal of the plug into and out of recessed areas of a component.
