Black Iron Hex Bush 1/4" X 1/8" M X F

A type of fitting used in plumbing systems. It has a hexagonal shape and is threaded on both ends. One end has larger threads and the other has smaller threads, allowing for a connection between pipes or fittings of different sizes. These hex bushings are commonly used to reduce the size of a threaded connection and create a smooth transition between pipe sizes while maintaining a secure and leak-resistant joint. They are often made from malleable iron and are suitable for various industrial and plumbing applications.
