Description
Overview:
This breather hose is a Genuine Honda part for the compact four‐stroke GX35 and GX35N engines. Made from moulded, oil‐ and heat‐resistant rubber, it routes crankcase vapours safely back into the intake system, helping to maintain correct internal pressure and clean running. By preventing pressure build‐up, it reduces the risk of oil mist leaks and supports stable idling and reliable starts. The hose is preformed to the correct shape for tidy routing on handheld tools and small machinery built around the Honda 35 cm3 engine platform. Identifiers include OEM No. 15721 Z0Z 000 and MPN 15721Z0Z000. It is a straightforward, like‐for‐like replacement for worn, hardened, or cracked hoses on equipment powered by Honda GX35 series engines.
Key Features:
- Genuine Honda part for assured compatibility and fit on GX35 family engines
- Preformed rubber hose maintains the correct routing and avoids kinks
- Oil‐ and heat‐resistant construction for long service life in tough environments
- Helps stabilise crankcase pressure for smooth running and consistent performance
- Reduces the chance of oil seepage and unwanted fumes around the engine
- Direct replacement; no modifications or special tools typically required
- Resists vibration and flexing common on handheld brushcutters and multi‐tools
- Supports proper ventilation to protect seals and gaskets from excess pressure
- Sized and shaped to integrate with the airbox/rocker cover connections as designed

Typical Applications:
Routine service replacement on Honda GX35‐powered brushcutters, strimmers, hedge trimmers, and multi‐tools. Ideal when the original hose shows signs of cracking, hardening, swelling, or leaks. Suitable for restoring correct ventilation after long storage or heavy use, helping maintain dependable starts and consistent operation in gardening, landscaping, construction site maintenance, and grounds care.
