Concentric Reducing Rubber Joint with Stainless Steel Flange for Noise Reduction and Shock Absorption
Concentric Reducing Rubber Joints are a key component of any piping system that requires reliable and effective diameter conversion, designed to provide superior vibration damping and isolation. This versatile product is ideally suited for applications in water supply systems, wastewater treatment plants and industrial pipelines where the diameter of the joint needs to be varied. Its unique construction allows for axial and lateral movement to compensate for expansion and contraction, as well as misalignment and other dynamic stresses in piping systems.
