The Honda Q14-0000-029 Seal is a genuine OEM component designed for WDP20 and WDP30 diaphragm water pumps. As a direct Honda OEM part, it is manufactured to the same specification as the original, ensuring a correct fit without modification. This seal is listed for both the WDP20 and WDP30 — verify your unit's serial number against the fitment table to confirm this is the right part for your pump. Honda supersedes parts at serial breaks, so checking your serial number before ordering is always the right move.
Key Features
- Genuine Honda OEM — sourced directly from Honda, built to the same specification as the original seal to maintain proper pump integrity
- Diaphragm Pump Fitment — listed for WDP20 and WDP30 diaphragm water pumps; confirm your serial number against the fitment table before ordering
- Critical Leak Prevention — a worn or damaged seal allows fluid to bypass internal pump components, reducing output pressure and risking contamination of the fluid path
In a diaphragm water pump, seals maintain the integrity of the fluid passages by preventing liquid from bypassing or escaping around moving components. The WDP20 and WDP30 use a reciprocating diaphragm driven by a crank and connecting rod to move water — seals within this system keep fluid contained and directed through the correct path. When a seal degrades, pump output drops and fluid can migrate to areas it should never reach, causing further internal damage.
