Square Head Pipe Plugs

Square head pipe plugs are made to plug holes in parts to stop fluids or gases from escaping and feature an external square drive for use of a wrench when tightening or loosening and male pipe threads for threading into internally threaded mating parts. They are made for use with air, natural gas, oil, and water and are made of brass for excellent resistance to corrosion.
