Stainless Steel Plugs are small, threaded components used to seal or close openings in pipes, tanks, and other industrial equipment. They are made of stainless steel, a material that is resistant to corrosion and rust, making them ideal for use in harsh environments and contact with liquids or gases. Stainless steel plugs come in a variety of shapes and sizes, including hexagonal, round, and square, to fit different types of openings.
