Rubber eccentric reducer joint, also called eccentric rubber expansiona joint, offset rubber connector, or eccentric rubber bellow, is a high-performance flexible connector designed to transition between pipes of different diameters while maintaining stable flow direction. Its offset structure prevents air accumulation and ensures smooth fluid passage, making it ideal for horizontal pipelines and systems where centerline misalignment must be corrected.

This rubber joint is manufactured using high-quality materials such as EPDM, NBR, or Neoprene, reinforced with steel wire or nylon fabric to enhance strength, durability, and pressure resistance. It provides excellent performance in absorbing vibration and noise, as well as resisting corrosion, aging, and mechanical stress.

Widely used in water treatment facilities, HVAC systems, chemical processing, and industrial drainage networks, the eccentric reducer joint meets international standards (ANSI, DIN, JIS). It is a preferred choice for engineers requiring flexible, long-lasting, and secure pipeline connections in demanding environments. Optional flange sizes and custom rubber materials are available to suit project-specific needs.
