Auburn H24-15 Coupler

The Auburn H24-15 Coupler is a high-performance cast iron circulator coupling engineered for demanding HVAC and industrial heating applications. Designed as a rugged C.I. spring coupler, this component ensures a precise and secure mechanical connection between the motor and the pump shaft. It features reinforced springs and a heavy-duty cross bar, specifically optimized for 1/2-inch shafts in 1/12 HP and 1/6 HP circulator motors. This HVAC replacement part is built from robust cast iron to withstand high-torque environments while providing the necessary flexibility to absorb startup shocks and reduce vibration. By maintaining exact alignment, the Auburn H24-15 prevents premature wear on bearings and seals, ensuring the long-term efficiency of your hydronic system. Whether used in boilers, furnaces, or commercial pumping stations, this OEM-quality coupling provides the durability required for continuous operation in extreme thermal conditions.
