Description
Mueller Streamline 521-810 is a 3 in. black iron plug with male pipe threads (MIP).
A plug closes off the end of a female threaded fitting or pipe, for example to cap a tee or coupling opening or to seal a line for pressure testing. Black iron fittings are commonly used in gas, heating and other non-potable piping systems.
Confirm the 3 in. size matches the female opening you are plugging, and use a thread sealant or tape that is rated for the service, such as gas or water. Check the catalog, item data and warranty documents below for details.
