Grooved Concentric Reducer Features
Grooved concentric reducer  is called a "concentric" reducer because it reduces the diameter of the pipe in a symmetrical and concentric manner, meaning that the centerline of the two pipes remains aligned.
The term "grooved" refers to the method of connecting the reducer to the pipes, which is by means of a mechanical coupling that uses a set of grooves on the ends of the pipes and the fitting. The grooves are typically cut into the pipe ends using a specialized tool, and the coupling is then clamped onto the grooves using bolts or a similar mechanism.
Grooved concentric reducers are commonly used in industrial and commercial piping systems where the diameter of the pipes needs to be reduced to accommodate changes in flow rate or pressure. They are often made of materials such as ductile iron, stainless steel, or carbon steel, and are available in a range of sizes and pressure ratings to suit different applications.
