The Honda 78313-YH4-610 Coupling Gasket is a genuine OEM replacement designed for the WX10 and WX15 water pumps. As a factory-sourced component, this gasket meets the original design tolerances Honda specifies for these compact pumps. Verify part number 78313-YH4-610 against your unit's serial number using the fitment table before ordering, as Honda supersedes parts at serial breaks and more than one coupling gasket variant may apply to your model.
Key Features
- Genuine OEM Sealing Integrity — sourced directly from Honda, this Coupling Gasket is made to the exact material and dimensional specification required to maintain a leak-free seal at the coupling joint on WX10 and WX15 pumps.
- Direct OEM Replacement — replaces the original gasket without modification, restoring the coupling connection to factory condition and eliminating seepage that can compromise pump output.
- WX10 and WX15 Fitment — confirmed for Honda WX10 and WX15 water pumps; cross-reference your serial number with the fitment table to ensure this is the correct coupling gasket for your specific unit.
The coupling gasket forms a pressure-tight seal at the connection point between the pump's coupling assembly and the adjacent housing or plumbing interface. When the gasket is intact, it prevents water from bypassing or leaking at the joint, allowing the WX10 or WX15 pump to maintain its rated flow and pressure. A cracked, compressed, or deteriorated gasket will allow water to seep past the coupling face, reducing pump efficiency and potentially causing moisture damage to surrounding components.
