The Honda 78114-955-000 Outlet Gasket is a genuine OEM replacement designed for the WA30 water pump. As a factory-original component, this gasket is manufactured to Honda's exact tolerances, ensuring a proper seal at the pump outlet without rework or shimming. Confirm part number 78114-955-000 against your unit's serial number and parts diagram before ordering to ensure this is the correct gasket for your configuration.
Key Features
- Genuine OEM Sealing Integrity — factory-original gasket material and profile engineered to hold a leak-free seal at the outlet port under the pressures a WA30 pump generates
- Direct-Fit Replacement — matches the outlet flange geometry of the WA30 water pump exactly, so installation goes straight in without trimming or adapting
- WA30 Water Pump Fitment — sourced and verified for the Honda WA30; check your serial number against the fitment table to confirm applicability to your specific unit
- Leak Prevention — a worn or damaged outlet gasket allows pressurized water to bypass the flange joint, reducing pump output and potentially damaging surrounding components; replacing it restores full discharge flow
The outlet gasket sits between the pump's discharge port and the outlet fitting, creating a pressure-tight seal that keeps pumped water moving through the intended flow path rather than escaping at the joint. On a centrifugal pump like the WA30, even a minor leak at the outlet flange reduces discharge pressure and flow rate, which directly undermines the pump's ability to move water at rated capacity. When this gasket deteriorates, hardens, or is damaged during service, replacing it with a genuine OEM part restores the sealed connection and brings the pump back to full working performance.
