The Pool Tool 127 Closed Impeller Wrench is a robust, technician-grade tool designed to lock into the vanes of closed-face pump impellers, enabling safe and stable removal or installation. Its precisely machined engagement points prevent slippage and reduce the risk of cracking impellers or stressing the pump’s motor shaft. Built from strong, corrosion-resistant metal, the wrench endures regular professional use in chemical and moisture-heavy pump environments. Suitable for pool and spa pumps that rely on closed impellers, the 127 wrench helps technicians break loose stubborn components and complete repairs with greater speed and confidence.
