2-1/2" NPSC x 1-1/2" NPSC 125lb Galv Cast Iron Hex Bushing

The 2-1/2" NPSC x 1-1/2" NPSC 125lb Galv Cast Iron Hex Bushing is a plumbing fitting commonly used in various industrial and commercial applications. Historically, cast iron has been widely utilized in plumbing applications due to its durability and resistance to corrosion. The manufacturing of cast iron fittings dates back to the late 18th century, where they gained prominence for their strength and ability to withstand high pressures. This specific hex bushing is designed to connect two different sizes of pipes, allowing for the transition between larger and smaller pipe diameters. It is made of galvanized cast iron, which provides enhanced protection against rust and ensures longevity in both water and gas line installations. The product is classified under the National Pipe Thread standard (NPSC), making it compatible with other NPSC fittings, which are commonly used in plumbing systems. The 125lb rating indicates its suitability for moderate pressure applications, typically found in heating, plumbing, and irrigation systems. Its hexagonal shape facilitates easy gripping and installation using a wrench, which is essential for tight and secure connections. The use of a domestic product also suggests that it is manufactured in compliance with strict quality control standards, providing reliability for professional and DIY users alike.
