The Honda Q14-0001-194 Plug is a genuine OEM replacement built for the WDP30 diaphragm water pump. Sourced directly from Honda, this plug is an exact match for the original component — ensuring a proper, leak-free fit without guesswork. If you need to verify fitment for your specific unit, check your pump's serial number against the fitment table before ordering.
Key Features
- Genuine Honda OEM — supplied by Honda to the same specification as the plug fitted at the factory, so the seal and fit match what the WDP30 was built around
- Exact Replacement — designed specifically for the WDP30 diaphragm water pump, this plug installs directly in place of the original with no adaptation needed
- Serial Number Matters — Honda updates parts at production breaks, so confirm your pump's serial number against the fitment table to ensure part number Q14-0001-194 is the correct version for your machine
A plug in a diaphragm water pump seals an opening in the pump body — whether a port, access point, or fluid passage — keeping the pump's internal system closed and pressurized during operation. On a diaphragm pump like the WDP30, maintaining sealed fluid passages is essential: the reciprocating diaphragm relies on a closed system to move water efficiently, and a missing or failed plug can cause pressure loss, leaks, or contamination of the fluid path. Replacing a worn or damaged plug with the correct OEM part restores that integrity and keeps the pump performing as intended.
