The Honda 91351-YG4-000 O-Ring (232X3.5) is a genuine OEM sealing component designed for the WB30 water pump. As a direct Honda OEM part, it is manufactured to exact dimensional tolerances, ensuring a proper sealing fit where the original was installed. Confirm part number 91351-YG4-000 against your unit's parts diagram before ordering, as Honda uses multiple O-ring sizes across the WB30 line and the 232X3.5 size designation identifies this specific variant.
Key Features
- OEM Sealing Integrity — manufactured to Honda's exact dimensional specification for this O-ring position, delivering the sealing performance the WB30 water pump requires
- Size-Specific Variant — the 232X3.5 designation identifies both the inside diameter and cross-section; match this to your parts diagram to confirm you have the correct O-ring for your application
- Direct OEM Replacement — sourced from Honda's own parts program, this component drops into the original location with no modification needed to restore proper pump function
- WB30 Water Pump Fitment — listed for the Honda WB30 water pump; verify your unit's serial number against the fitment table to confirm compatibility with your specific production range
An O-ring is a circular elastomeric seal used to prevent fluid from passing between mating surfaces or through a bore. In a water pump like the WB30, O-rings are used at joints, ports, and housings where a reliable, pressure-resistant seal is essential to keep water moving through the pump and out of areas where leakage would cause performance loss or damage. When an O-ring deteriorates, hardens, or is cut during service, the result is a visible leak or a drop in pump output — replacing it promptly with the correct OEM part restores the seal and returns the pump to full working condition.
