The Honda 78114-YH5-610 Outlet Gasket is a genuine OEM replacement designed for the WX15 water pump. As an authentic Honda part, it is manufactured to the same specifications as the original, ensuring a correct, leak-free fit at the pump outlet. This gasket is the right choice when servicing or rebuilding a WX15 and the original seal shows wear, compression set, or damage.
Key Features
- Genuine OEM Seal Integrity — sourced directly from Honda, this gasket is formed to the exact profile and material grade required at the WX15 outlet port, delivering the tight seal the original design calls for.
- Direct-Fit Replacement — made to match the original outlet gasket dimensions exactly, so this part drops into place without trimming or modification during a pump service.
- Fits the WX15 Water Pump — verify your unit's serial number against the fitment table to confirm this is the correct gasket for your production run, as Honda updates parts at serial breaks.
- Stops Outlet Leaks — a compressed or cracked outlet gasket allows water to escape at the discharge connection, reducing pump output and creating a wet hazard at the work site; replacing it restores full pressure delivery.
The outlet gasket forms a pressure-tight seal between the pump's discharge port and the outlet fitting, preventing water from bypassing the connection under operating pressure. On a compact pump like the WX15, even a minor leak at the outlet can measurably reduce flow and pressure at the hose. When the gasket degrades — through heat cycling, chemical exposure, or simple compression set — the result is visible weeping or a steady drip at the outlet joint that worsens under load.
