Key Features
- Genuine Honda OEM — sourced directly from Honda, this washer matches the original specification for WDP20 and WDP30 diaphragm water pumps.
- Direct-Fit Replacement — designed as a drop-in replacement, this part installs without modification to restore proper function.
- Verify Before Ordering — Honda updates parts at serial number breaks, so check your pump's serial number against the compatibility table to confirm this is the right washer for your machine.
A washer distributes the clamping load of a fastener across a broader surface area, preventing the fastener from pulling through or damaging the material it secures. In a diaphragm water pump such as the WDP20 and WDP30, washers play a quiet but essential role in keeping assemblies correctly torqued and leak-free under the repetitive mechanical stress of pump operation. A missing or damaged washer can allow fasteners to loosen over time, leading to misalignment, leaks, or premature wear of surrounding components.
