The B&K 1-1/4-in x 1-in FIP Black Iron Reducing Coupling is a dependable fitting designed to connect two male-ended pipes of differing diameters. Made from black malleable iron, this coupling is engineered for durability and performance in demanding environments. It is ideal for industrial and residential applications involving non-potable fluids such as grease, oil, lubricants, liquefied petroleum (LP) gas, natural gases, steam, and diesel.

This coupling is part of B&K’s extensive line of black iron fittings, which are rigorously tested to meet the highest standards of trade professionals. The malleable iron construction allows for a secure seal due to the relative softness of the metal, and the threaded ends conform to ANSI B1.20.1 standards. Dimensions meet ASME B16.3 specifications, ensuring compatibility and reliability in various piping systems.

Whether used in mechanical systems, fuel transport, or custom plumbing projects, this reducing coupling offers a robust solution for adapting pipe sizes while maintaining system integrity.
