The Honda 15721-Z44-A40 Breather Tube is a genuine OEM component designed for EB2200 and EU2200 inverter generators. As a direct OEM replacement, this part is built to Honda's original specifications, ensuring it seats and routes exactly as the factory-installed tube does. Confirm fitment by checking your generator's serial number against the compatibility table before ordering.
Key Features
- Genuine OEM Sourcing — manufactured to Honda's original specifications, so the tube dimensions, routing, and connection points match what came off the production line
- Exact-Fit Replacement — designed specifically for EB2200 and EU2200 inverter generators; installs without modification using the original mounting points
- Serial Number Verification Recommended — Honda supersedes parts at production breaks, so cross-check your generator's serial number against the fitment table to confirm part number 15721-Z44-A40 is correct for your unit
- Crankcase Ventilation Integrity — a properly functioning breather tube keeps crankcase pressure regulated; a cracked or blocked tube can cause oil leaks, rough running, or excessive oil consumption
The breather tube routes crankcase vapors away from the engine's internal cavities, allowing pressure that builds during normal combustion to vent in a controlled way. Without a properly sealed and unobstructed breather tube, crankcase pressure rises, forcing oil past seals and into areas where it does not belong, often leading to oil leaks, fouled air filters, or a rough-running generator. Replacing a damaged or degraded tube restores the engine's ventilation system to proper operation and protects against the secondary damage that uncontrolled pressure buildup can cause.
