The Honda 78311-YH4-610 Hose Coupling is a genuine OEM component designed for WX10 and WX15 water pumps. As a direct Honda OEM part, this coupling is manufactured to the same specifications as the original, ensuring a proper connection between hose and pump without improvisation or adaptation. This part is built for the WX10 and WX15 — confirm your pump's serial number against the fitment table to make sure this is the correct coupling for your unit.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this coupling matches the original specification for a secure, leak-free hose connection on your water pump.
- Direct Fitment — engineered specifically for WX10 and WX15 water pumps; installs in place of the original with no reworking of the hose connection.
- Serial Number Verification Recommended — Honda updates parts at production breaks, so cross-check your pump's serial number against the fitment table before ordering to confirm this is the right coupling.
The hose coupling is the connection point between the pump's discharge or suction port and the attached hose, forming a sealed interface that keeps water flowing efficiently through the system. A failed or damaged coupling allows air to enter the suction side or water to leak at the discharge, both of which reduce pump output and can cause the pump to lose prime. Replacing a worn coupling with a genuine Honda part restores the integrity of that connection and keeps the pump performing as intended.
