The Honda 15721-ZT3-000 Breather Tube is a genuine OEM component designed for EU1000 and EX700 inverter generators. As a direct Honda OEM part, it meets the same standards as the original tube fitted at the factory, ensuring proper routing and sealing within the crankcase ventilation system. Confirm your generator's serial number against the fitment table before ordering, as Honda does update part numbers at production breaks.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this Breather Tube is an exact match for the original, maintaining the correct internal diameter and routing geometry the crankcase ventilation system depends on.
- Crankcase Ventilation Integrity — a correctly seated breather tube keeps crankcase pressure properly vented, preventing oil mist from backing up into areas where it can cause starting issues or fouled components.
- Fits EU1000 and EX700 Inverter Generators — designed specifically for these Honda inverter generator models; always cross-reference your serial number with the fitment table to confirm this is the correct part for your unit.
The breather tube is part of the crankcase ventilation system, channeling blow-by gases and oil mist away from the crankcase and routing them back into the air intake to be burned cleanly. This controlled venting prevents pressure buildup inside the engine, which can force oil past seals and gaskets and lead to leaks or excessive oil consumption. A cracked, kinked, or deteriorated breather tube disrupts this balance, often showing up as oil weeping from the engine or a rough-running generator.
