This rubber expansion joint features a double ball design that provides superior flexibility and motion compensation compared to single ball joints. Angular and parallel misalignment of piping can be achieved, while also absorbing noise, isolating vibrations and reducing sound transmission through the piping system. Double ball flexible rubber couplings excel in applications that require a high degree of flexibility and are the ideal solution for movement, settlement or thermal expansion and contraction systems.
1.This rubber expansion joint features a double ball design that provides superior flexibility and motion compensation compared to single ball joints.
2.Double ball flexible rubber couplings are not only practical but also easy to install.
3.The product is available in a wide range of materials to suit different media.
