Pipe plugs are cylindrical metal fittings with a taper‑threaded shaft at one end and a drive section at the other. It is a simple and cheap method for connecting a pipe. Tapered threads have a slight cone profile, causing the male and female threads to compress against each other to form a tight seal. In use, the male threaded shaft is screwed into the female thread of a pipe or housing.
Stainless Steel threaded plugs can be inserted into threaded openings and seal the ends of pipes, providing a more stable and consistent seal and preventing dirt, moisture, or other contaminants from affecting your threads. They come in a piece body design and the easy-to-replace plug assembly makes these industrial pipe fittings very easy to maintain and clean.
Generally, these pipe plugs are often plated with chrome or nickel for a finish and better resistance to corrosion.
The primary role of a pipe plug is to block the flow of fluids, but they are also used to prevent dirt and other contaminants from entering an opening in a pipe. They are used in industries ranging from plumbing and construction to hydraulics, gas and oil transportation, agriculture, food and beverage manufacturing, and industrial chemical processing, etc.
