The Honda 360408006 Mechanical Seal is a genuine OEM component designed for WSP53 and WSP73 submersible electric water pumps. As a direct OEM replacement, this seal is manufactured to Honda's exact specifications, ensuring a proper fit with no guesswork. Confirm your pump's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and this seal may vary between production runs. This part is engineered to restore the watertight integrity that keeps your submersible pump operating correctly.
Key Features
- Genuine OEM Sealing Performance — sourced directly from Honda, this mechanical seal delivers the precise mating surfaces and sealing geometry required to prevent water ingress into the pump's motor cavity.
- Direct Replacement Fit — built to the same specifications as the original, this seal installs directly into WSP53 and WSP73 submersible electric water pumps without modification.
- Serial Number Verification Recommended — Honda updates parts at production breaks, so cross-reference your pump's serial number with the fitment table to confirm part number 360408006 is correct for your unit.
- Protects the Motor from Water Damage — a worn or failed mechanical seal allows water to migrate toward the sealed electric motor, leading to motor failure and costly repairs. Replacing this seal promptly restores the barrier between the wet end and the motor.
A mechanical seal is the primary barrier that separates the pump's wet end — where water flows through the impeller — from the sealed electric motor housing. Unlike a simple gasket, a mechanical seal uses precision-lapped mating faces held in constant contact to prevent water from tracking along the pump shaft and reaching the motor. When this seal wears or fails, water bypasses the rotating faces, infiltrates the motor cavity, and can cause electrical failure or seize the motor entirely. Replacing it with a genuine Honda part restores the original sealing performance and extends the service life of the pump.
