Tube and Pipe purging plugs are another option to create barriers for pipe, tube and fitting purging. They are ideal for short-diameter pipes, tubes, and for pipes that branch off into multiple ends requiring sealing.
Purge plugs can be used for sealing outlets when purging small-length tubes, as low pressure test plugs for pipe joints, and to keep the inside of the tube clean and free of contaminants. Arc-Zone.com carries a variety of plugs engineered to deliver an air-tight seal for pipe purging and for keeping out unwanted air during welding. Some have a hallow shaft and a sealing end cap, through which a gas inlet hose or vent hose may be connected.
