Reznor 112042 Coupling 321042-401 Precise 1/4" NPT connections ensureThe Reznor 112042 Flexible Coupling is a critical mechanical interface designed for 5 16" shafts, commonly utilized in direct drive blower assemblies and motor to pump linkages across Reznor's unit heater lineup. This flexible coupling 5 16" is engineered to mitigate shaft misalignment, which reduces vibration and prevents premature bearing failure in high torque HVACR applications. Built with a resilient center member and durable hubs, the 112042
