The unique angle-pad design of the Zero-Flex® Style 07 coupling adjusts to standard pipe and roll or cut groove tolerances, positively clamping the pipe to resist flexural and torsional loads. The wider key section fills more of the groove area. The Victaulic standard rigid coupling offering is the Style 107 installation-ready rigid coupling product line. For all available sizes, the Style 107 is the standard rigid coupling Victaulic supplies in North America for piping systems using Grade EHP or T gaskets. Contact Victaulic for further details. Style 07 couplings are rated up to 750 psi/5175 kPa, dependent on size, for 1 to 12 in/25 to 300 mm piping systems. Rigid couplings provide rigidity for valve connections, machinery rooms, fire mains, and long straight runs. Support and hanging requirements correspond to ASME B31.1 Power Piping Code, ASME B31.9 Building Services Code and NFPA 13 Sprinkler Systems. Angle-pad design permits assembly by removing one nut/bolt and scissoring housing over gasket. This reduces the number of components to handle during assembly, speeds and eases installation.
