Abstract
A mechanical packing system for use for a device allows one or more packing rings to be installed one at a time and die formed in place. A reversible, detachable flange having a key offset from the center is inserted into a key slot of the hub of the mechanical packing system which is also offset during this installation process. When the device is operated, the flange is detached from the hub rotated 180° and the key of the flange is then inserted into the key slot of the hub. A spacer with integral lantern ring and internal bore surface which reduces or prevents marring or galling. A stuffing box of sufficient length to eliminate the need for a spacer or unneeded packing rings.
