Crown Engineering 10010 Coupler 319847-401 a lack of continuity indicatesThe Crown Engineering 10010 Coupler is a professional grade Spiralink pump coupler designed for high torque hydronic heating systems. Specifically engineered for 1 12 to 1 3 HP motors, it features a unique single spring spiral design that provides 3 dimensional flexibility to compensate for shaft misalignment between the motor and the pump head. Unlike older, multi part "fly away" couplings, this one piece HVAC pump coupling eliminates friction
