ABSTRACT:
A shipping plug is disclosed herein. The shipping plug is formed from a cylindrical member that is configured to be operatively disposed within a bore of a component to create a seal therewith. The cylindrical member is a resilient material, and has an upper wall, a lower wall, and a circumferential side defined between the upper and lower walls. A recess is defined in the upper wall. The recess includes a bottom end and at least one wall extending between the bottom end and the upper wall. The recess is configured to operatively receive a complementarily shaped rod which selectively distorts the circumferential side of the cylindrical member in response to a twisting or rotating action exerted thereon to temporarily release the seal.
