The ASTM F304L Concentric Reducer is a pipe fitting designed to connect two pipes of different diameters while maintaining a uniform centerline. Made from F304L stainless steel, it offers excellent resistance to intergranular corrosion due to its low carbon content, making it suitable for applications that involve welding. This reducer is commonly used in chemical processing, food and beverage, and pharmaceutical industries where seamless flow transitions and durability are critical. Its concentric design ensures smooth fluid flow without causing turbulence or pressure drops.
