The Honda 78104-YG4-610 Outlet (NPTF) is a genuine OEM discharge outlet fitting designed for the WB30 water pump. As a direct Honda OEM component, this part is produced to the same specifications as the original, ensuring a proper connection at the pump's discharge port. Verify your pump's serial number against the fitment table before ordering to confirm this is the correct outlet for your unit.
Key Features
- Genuine OEM Discharge Fitting — sourced directly from Honda, this outlet is manufactured to the same specification as the part that left the factory, ensuring the NPTF thread form mates correctly with your discharge plumbing.
- NPTF Thread Form — the National Pipe Taper Fuel (NPTF) thread profile is designed to make a pressure-tight seal through thread interference alone, which is critical at the discharge side of a working water pump.
- Built for the WB30 Water Pump — engineered specifically for the WB30, this outlet matches the discharge port geometry of that pump without rework or adaptation.
- Check Your Serial Number — Honda updates parts at production serial breaks, so confirm your WB30's serial number against the fitment table to be sure part number 78104-YG4-610 is the right outlet for your specific unit.
The outlet is the threaded discharge fitting through which water leaves the pump after passing through the impeller and volute. It connects the pump body to the discharge hose or hard plumbing, and its thread form determines how that connection seals under pressure. A cracked, corroded, or cross-threaded outlet can cause leaks at the discharge point that reduce flow volume and allow water to escape before it reaches its intended destination. Replacing a damaged outlet with the correct genuine OEM part restores a leak-free discharge connection and keeps the WB30 operating at full pumping capacity.
