A packing sealer plug for use with valve flanges or the like. The packing sealer plug is adapted to be used in tapped openings leading to the interface between the valve flanges or other types of fittings in which packing is to be introduced by a high pressure packing gun. The plug is comprised of an externally threaded end insertable in the opening and an axial passage way leading to an opposite end of the plug which has a threaded opening adapted to receive a nozzle of the packing gun or the like for introduction of the packing. The end of the plug adjacent the threaded opening has a hexagonal square or circular exterior for reception of a wrench for connecting the plug to the flange opening. A cut-off passage way intersects with the axial passage way radially and is threaded to receive a cut-off bolt to seal the plug. The externally threaded end of the plug has a solid end with a circumferential groove adjacent to it and radial ports communicating with the axial passage way in order that packing can be expelled through the ports and the grooves substantially 360 degrees around the plug to insure even distribution of the packing.
A packing and sealer plug for entry of packing into a fitting and sealing the same, said plug comprised of a body having an externally threaded portion at one end adapted to engage an internally threaded fitting, said plug having an internally threaded opening at a second end adapted to receive a threaded nozzle of a packing gun or the like for admission of packing thereto, a passageway connecting said internally threaded opening with radial ports at the end of said externally threaded portion, said externally threaded end portion being provided with an external circumferential groove communicating with said radial ports for distribution of said packing uniformly around the end portion of said plug.
