The Honda 91353-YH4-610 O-Ring (36.5X5.7) is a genuine OEM replacement designed for Honda WX10 water pumps. As a direct Honda OEM part, it is manufactured to the exact dimensions and material specification the WX10 was engineered around, ensuring a proper seal every time. Confirm your unit's serial number against the fitment table before ordering to be certain this is the correct O-ring for your application.
Key Features
- Exact Sealing Geometry — at 36.5 x 5.7 mm, this O-ring matches the precise cross-section and inner diameter Honda specified for the WX10, delivering a consistent, leak-free seal at the intended interface
- Genuine Honda OEM Part — sourced directly from Honda, carrying part number 91353-YH4-610, so there is no guesswork about whether dimensions or compound grade will match the original
- WX10 Water Pump Fitment — listed for the Honda WX10 lightweight water pump; check your serial number against the fitment table to confirm this is the right variant for your machine
- Leak Prevention — a worn or damaged O-ring allows water or air to bypass the sealed joint, reducing pump output pressure and flow; replacing this component restores the integrity of the pump's circuit
An O-ring is a looped elastomeric seal seated in a machined groove, compressed between two mating surfaces to prevent fluid from escaping the joint. In a water pump like the WX10, O-rings are used at key junctions throughout the pump body to maintain a closed, pressurized system. When an O-ring hardens, cracks, or takes a set from age or chemical exposure, the seal fails — resulting in leaks, loss of prime, or reduced pumping performance that a fresh OEM O-ring corrects.
