Key Features

- Direct OEM Replacement — engineered as a drop-in fit for the WT40 water pump, restoring the discharge connection to its original working condition

The outlet on a water pump is the discharge port through which pressurized water exits the pump housing and enters the discharge hose or piping. On the WT40, it forms the critical connection between the pump volute and the downstream system, so a correctly sealed and undamaged outlet is essential for maintaining full flow and pressure. A cracked, worn, or improperly sealed outlet will cause pressure loss, leakage at the discharge point, and reduced pumping performance.
