B&K 521-383Click To Copy Black Malleable Iron Reducing Coupling, 2" x 1/2"

This B&K reducing coupling, model number 521-383, is manufactured from malleable iron with a black finish, commonly known as black oxide. It is designed to connect pipes of two different nominal diameters, specifically reducing from a 2-inch pipe to a 1/2-inch pipe. The fitting features threaded ends (typically FNPT or NPT) for secure connections in various piping systems. It is rated for pressure class 150 lb and can withstand pressures up to 300 psi. This type of coupling is suitable for a wide range of applications including oil, gas, air, and general plumbing systems. Malleable iron fittings often comply with industry standards such as ASTM A197 for malleable iron castings and ASME B16.3 for malleable iron threaded fittings, with threads conforming to ASME B1.20.1.
