The B&K 2-in x 1-in FIP Black Iron Reducing Coupling is a high-performance fitting designed to connect two male-ended pipes of different diameters. Crafted from durable black iron, this coupling is ideal for industrial and residential applications involving non-potable fluids. It is commonly used in systems that transport lubricants, oils, greases, liquefied petroleum (LP) gases, and fuels, as well as in DIY projects requiring secure pipe connections.

This coupling belongs to B&K’s 150-lb class malleable fittings, which are known for their ability to form tight seals due to the relative softness of the metal. It is engineered to withstand pressures up to 500 PSI at temperatures of 150°F, making it suitable for demanding environments. The threaded ends are manufactured to ANSI/ASME B1.20.1 standards, ensuring compatibility and ease of installation. The product also meets ASTM and ASME standards, reflecting its quality and reliability.

Whether you're working on a mechanical system or a custom plumbing setup, this reducing coupling offers a dependable solution for adapting pipe sizes while maintaining system integrity.
