T&B Conduit FittingsRigid and Intermediate Metal Conduit FittingsTHE T&B ® HubNever before has a single hub fit like this one. Designed for unequalled performance. The innovative engineering of theT&B ®Hub will, quite simply, raise your performance expectations for threaded hubs. The revolution in hub design is here,and the fate of our competition is sealed.Figure 1 Figure 2 Figure 31. Sealing ring and groove withinnovative profile outperformsstandard 'O' ring design. Sealingring is captive before installationand resists buckling or slipping duringinstallation. The seal groove isdesigned for optimum compression ofthe sealing ring. The sealing ring isdesigned to provide a complete 360°seal, even when the conduit is notperpendicular with the enclosure. (SeeFigure 1)Throat Dia. E2. Locknut design with peripheralslots and a hexagonal/angledspline spaced every 30° enableseasy application of torque withwrench or hammer and screwdriver.(SeeFigures2&3)3.
