GRINNELL Flexible Couplings allow for pipe rotational movement and/or angular misalignment which aids in system installation. These flexible couplings also allow for pipe axial movement providing the option to reduce stresses induced by pipe system thermal expansion and contraction. Flexible couplings can be used as system noise and vibration attenuators.
