Iron mouth guards and pipe braces are two different pipe fittings, each with different functions and uses. An iron mouth guard is a protective device that is installed at the end of a pipe and is usually made of metal material. Its main function is to protect the pipeline from damage caused by external factors, such as preventing the pipe from being hit, worn or corroded. At the same time, the iron guard can also effectively prevent the leakage of water or gas inside the pipeline. When installed, the iron guard usually fits tightly with the end of the pipe to ensure its sealing performance. 
A pipe brace is a tool used to support and hold pipes. It is usually made of metal materials and has enough strength and stability to be able to effectively support the pipe and keep its position fixed. Pipe braces are typically installed in the middle of the pipe to prevent the pipe from bending, deforming, or shifting under the action of gravity and other external forces. When installed, pipe supporters are often used in conjunction with the support structure inside the pipe to ensure its support. 
While iron guards and pipe braces are pipe fittings, they differ in their usage scenarios and functions. Iron guards are mainly used to protect pipelines from damage and leakage;Pipe braces, on the other hand, are mainly used to support and fix pipes to prevent them from deforming and dislodging. In practical applications, according to different needs and scenarios, suitable pipe fittings can be selected to ensure the normal operation and service life of the pipeline.
