The Honda 78112-YF2-505 End Plate Gasket is a genuine OEM component designed for WX15 water pumps. As a direct Honda replacement, this gasket is produced to the exact specifications required by the WX15, ensuring a proper seal at the end plate. Confirm part number 78112-YF2-505 against your pump's serial number using the fitment table before ordering.
Key Features
- Genuine OEM Sealing Integrity — manufactured by Honda to the exact tolerances required for a leak-free end plate seal on the WX15, so the pump delivers its rated flow without losing prime or weeping at the joint.
- Direct OEM Replacement — engineered to drop into the existing end plate assembly without modification, restoring the pump to its original operating condition.
- Verify Your Serial Number — Honda updates part specifications at production breaks, so cross-check your WX15 serial number against the fitment table to confirm this is the correct gasket for your unit.
The end plate gasket forms a pressure-tight seal between the pump's end plate and the pump body, keeping water contained within the volute and preventing loss of prime. On a centrifugal pump like the WX15, even a minor leak at this joint disrupts the internal pressure the impeller needs to move water efficiently. A worn, compressed, or damaged gasket allows air to enter the system, causing the pump to lose suction, run dry, and potentially overheat — making timely replacement critical to keeping the pump operating at full capacity.
