DN50 2'' EPDM/NBR Thread Connection Double Spheres Rubber Expansion Joint Connector
DN50 2''
The DN50 (2") threaded double-sphere rubber expansion joint is a flexible connector designed to absorb vibration, noise, thermal expansion, and pipe misalignment in piping systems. With dual spherical rubber bodies and threaded connections, it provides greater movement capability than single-sphere models, making it ideal for compact installations where space and flexibility are critical.
