The Honda 91352-YH4-610 O-Ring (140X3.5) is a genuine OEM replacement designed for WX10 water pumps. As a factory-original component, this O-Ring is manufactured to the same specifications as the part that shipped with the pump, ensuring the sealing integrity Honda engineers designed it to deliver. Confirm your unit's serial number against the fitment table before ordering, as Honda periodically supersedes parts at production breaks.
Key Features
- Genuine OEM Sealing Performance — manufactured to Honda's original dimensions and compound specification, so this O-Ring seats and seals exactly as the factory intended for WX10 water pumps
- Exact Dimensional Fit — the 140X3.5 designation identifies the precise inner diameter and cross-section; matching this to your pump's groove is critical to achieving a leak-free seal
- Serial Number Verification Recommended — Honda supersedes sealing components at production breaks, so confirm your WX10 serial number against the fitment table to ensure this is the correct listing for your unit
An O-Ring is a continuous loop seal that sits in a machined groove, compressed between two mating surfaces to prevent fluid from passing through the joint. In a water pump like the WX10, O-Rings maintain a watertight boundary between assembled housings and passages, keeping pump pressure where it belongs and preventing external leaks. When an O-Ring hardens, cracks, or deforms over time, that seal breaks down — resulting in visible leaks, reduced pump pressure, or water bypassing internal passages — and the ring must be replaced to restore full pumping performance.
