The Honda Q14-0000-026 Gasket is a genuine OEM replacement designed for WDP20 and WDP30 diaphragm water pumps. As a Honda OEM part, it is manufactured to the exact specifications required for proper sealing in these pumps, ensuring the correct fit without the guesswork that can come with non-OEM alternatives. This gasket is listed for both the WDP20 and WDP30 — verify your unit's serial number against the fitment table to confirm the correct application before ordering.
Key Features
- Genuine OEM Sealing Integrity — manufactured by Honda to deliver the correct sealing surface geometry and compression characteristics required in diaphragm pump assemblies
- Direct OEM Replacement — sourced directly from Honda, this gasket installs as a drop-in replacement with no alterations needed to the pump assembly
- Fits WDP20 and WDP30 Diaphragm Water Pumps — listed for both models; confirm your pump's serial number against the fitment table to ensure this is the correct part for your unit
- Prevents Fluid Bypass — a failed or damaged gasket in a diaphragm pump allows fluid to bypass the intended flow path, reducing output pressure and efficiency; replacing a compromised gasket restores the pump to proper operating condition
In a diaphragm water pump such as the WDP20 and WDP30, gaskets form the critical seals between mating surfaces throughout the pump body. When a gasket deteriorates, cracks, or is damaged during service, the pump loses the ability to create and sustain the pressure differential it needs to move water effectively. Replacing a worn gasket with a Honda OEM part restores the integrity of those sealing surfaces and returns the pump to full performance.
