Square and hex plugs are types of pipe fittings used in plumbing or industrial applications to close off the ends of pipes or fittings. These plugs have different shapes at their ends, providing a means to seal or cap off a pipe's opening securely.
Square Plug: A square plug, as the name suggests, has a square-shaped head at one end. This square head allows for easy gripping and turning using a wrench or other suitable tools to tighten or loosen the plug into the pipe's threaded opening. It provides a secure closure for pipes or fittings.
Hex Plug: A hex plug, on the other hand, has a hexagonal (six-sided) head at one end. Similar to the square plug, the hex head design facilitates the use of a wrench or spanner for installation or removal. The hex shape provides a more secure grip, making it easier to tighten or loosen the plug.
Both square and hex plugs are available in various sizes and materials like brass, stainless steel, or other metals, and they are used to close off pipes temporarily or permanently, preventing leaks and controlling the flow of fluids within a plumbing or industrial system.
