About this item

The B&K 511-222HC is a 3/8-inch Female Iron Pipe (FIP) black iron merchant coupling, designed to create a secure connection between two pipes of matching diameter. Manufactured from 150-lb class malleable iron, this coupling is ideal for use in a wide range of industrial and mechanical applications where durability and pressure resistance are essential.

Its threaded ends comply with ANSI/ASME B1.20.1 standards, ensuring a tight and reliable seal. The relative softness of the malleable iron helps enhance sealing performance, especially in high-pressure systems. This coupling is suitable for transporting lubricants, oils, greases, LP gases, natural gases (e.g., nitrogen, oxygen), steam, and diesel, and is also popular for custom DIY piping projects.
