Stainless Steel Single Sphere Molded Rubber Expansion Joints

The single sphere rubber expansion joint is a high-elasticity, high-sealability, material-resistant, and aging-resistant three-way connector. Also known as a rubber expansion joint, rubber flexible joint, or rubber compensator, the single sphere type rubber expansion joint is an elastic connecting element used in piping systems. Its primary function is to absorb the expansion and contraction of the piping system caused by temperature changes, vibrations, or displacements, there by reducing vibration and noise, protecting the piping system from damage, and improving the operational efficiency and safety of the system. The single sphere flexible rubber joint is typically made of rubber materials such as Ethylene Propylene Diene Monomer (EPDM) or Natural Rubber (NR), lined with reinforced fiber mesh to enhance strength and durability. Its structure includes one or more rubber bellows that can compensate for displacements in axial, lateral, and angular directions. Compared to double spher…
