Threaded plugs are used to close boreholes with cylindrical internal thread. They are a type of pipe fittings used in the plumbing apparatus of both industrial and domestic water supply lines, machinery, and so on.
Features male National Pipe Taper (NPT) threads for closing the end of a female threaded pipe. Plugs are inserted into female pipes or fittings and connect with NPT threads, which create a tighter seal than straight threads. The tightness depends on the material, the pressure, the temperature as well as the material pairing.
The stainless steel threaded plugs are an easy and cost-effective way to plug your pipe. They are used for the ends of shafts, tubes, pipes, fittings, connectors, screws, bars, or other shapes.
These pipe plugs are often plated with chrome or nickel for a finish and better resistance to corrosion. They can resist corrosion caused by water, heat, saltwater, acids, minerals, peaty soils, etc.
These pipe plugs come in a piece body design and the easy-to-replace plug assembly makes these industrial pipe fittings very easy to maintain and clean.
