The Honda 15721-ZT3-T40 Breather Tube A is a genuine OEM component designed for the EU1000 inverter generator. As a direct Honda OEM part, it is manufactured to the same specifications as the original, ensuring a proper fit with no guesswork. Confirm your unit's serial number against the fitment table before ordering to make sure this is the correct tube for your EU1000.
Key Features
- Genuine Honda OEM Part — sourced directly from Honda, this breather tube meets the exact dimensions and routing requirements of the original component in the EU1000 crankcase ventilation circuit.
- Direct Replacement — designed to connect and route exactly as the factory tube does, with no trimming or adapting required.
- Serial Number Matters — Honda updates parts at production breakpoints, so check your EU1000's serial number against the compatibility table to confirm part number 15721-ZT3-T40 is correct for your unit.
- Ventilation Integrity — a cracked or deteriorated breather tube allows unmetered air into the crankcase ventilation system, which can cause oil consumption issues and rough running; replacing a failed tube restores proper crankcase pressure management.
The breather tube routes crankcase vapors away from the engine's crankcase and back into the combustion process, preventing pressure buildup inside the engine. In the EU1000 inverter generator, maintaining a sealed, intact breather tube keeps the crankcase ventilation system functioning correctly, which directly affects oil consumption and engine cleanliness. When this tube cracks, collapses, or pulls loose at its connection points, crankcase pressure can climb and oil mist may escape — signs that the tube needs immediate attention.
