An MDPE MTA refers to a Medium-Density Polyethylene (MDPE) Male Threaded Adapter. MDPE is known for its durability, flexibility, and resistance to chemicals. It is a type of compression fitting designed for connecting MDPE pipes to other components, such as valves, fixtures, or other pipes, that have female-threaded connections. They are suitable for connecting MDPE pipes to other components with female-threaded connections. The male threaded adapter part of the fitting has external threads, allowing it to be screwed into a corresponding female-threaded connection, such as the threaded end of a pipe or another fitting. MDPE MTA is commonly used in water supply systems where MDPE pipes are employed.
