SS SCREWED THREADED PIPE FITTINGS FOR SQUARE PLUG
Square plugs are designed to be fit into holes or cavities. They are used for the ends of shafts, tubes, pipes, fittings,
connectors, screws, bars, or other shapes. Pipe plugs are available in various shapes and materials as square Plug,
round plug, Hex. Plug. They also come in a variety of different cross sections.
Square plugs are used to stop fluid movement in the piping system. It has a male threaded end. The NPT (tapered)
thread connection makes it easy to assemble and disassemble during maintenance and installation.
