Key Features
- Genuine OEM Sealing Integrity — manufactured to Honda's exact dimensional specification, ensuring the O-Ring seats correctly and holds a leak-free seal under pump operating pressures
- Direct Replacement for the WT40 — engineered specifically for the Honda WT40 water pump, so this O-Ring installs without modification
- Serial Number Verification Recommended — Honda supersedes sealing components at production breaks, so cross-reference your pump's serial number against the fitment table to confirm this is the correct O-Ring for your unit
An O-Ring is a circular elastomeric seal used to prevent fluid from leaking past a joint or bore interface inside the water pump. In a pump like the WT40, O-Rings maintain a pressure-tight barrier at critical connection points, keeping water moving through the system rather than escaping around fittings or housings. When an O-Ring degrades, cracks, or takes a permanent set, it loses its sealing ability — leading to leaks, pressure loss, and potential damage to surrounding components.
