About this item

The B&K 2-in MIP Black Iron Plug (Model 521-808HN) is a square head plug designed to seal off female threaded fittings or pipes in industrial and mechanical systems. Made from black malleable iron, this plug is ideal for non-potable applications such as transporting lubricants, oils, greases, liquefied petroleum (LP) gases, and fuels. It is part of the 150-lb class malleable fittings and is engineered to perform under high pressure and temperature conditions.

This plug is not intended for potable water systems but is well-suited for use in steam, diesel, and various gas systems. Its threaded ends conform to ANSI/ASME B1.20.1 standards, ensuring a secure and leak-resistant connection. The relative softness of the metal enhances sealing performance, making it suitable for demanding industrial environments.
