Square Plug

Talk To An Expert

Galvanized square plugs are threaded fittings used to close off the end of a pipe run or fitting, providing a secure seal against leaks. The square head design allows for simple tightening or removal using standard tools. Their galvanized zinc finish makes them resistant to rust and corrosion, ensuring reliable service in outdoor water lines, gas piping, irrigation systems, and industrial plumbing networks. Square plugs are valued for their ease of use, durability, and long service life in environments where moisture or corrosive conditions are present.
