- The GRINNELL Figure 705 Flexible Coupling is capable of pressures ranging from full vacuum to 500 psi (34,5 bar) depending on pipe size and wall thickness. Up to 40% lighter than the Figure 707 coupling, and available with various gasket materials, it provides a proven dependable method of joining pipe and is suitable for use in a variety of applications ranging from -30 to 350 deg F. 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, an especially beneficial feature when used to connect a pump package.
