Description
Overview:
The Breather Tube for Honda GCV 160 and GCV 190 engines is a genuine Honda OEM hose that manages crankcase ventilation to keep the engine running smoothly. Made from flexible, oil- and heat-resistant rubber in a pre-formed shape, it routes vapour safely back to the intake, helping to prevent pressure build-up and oil leaks. This part is designed for walk‐behind lawnmowers and similar equipment using the Honda GCV/GSV family of engines, including popular machines such as the HRX476 and HRG536 ranges. Supplied under Honda part number 15721-ZM0-000 (also 15721 ZM0 000), it offers the correct fit and routing, ensuring reliable sealing and long service life when replacing a hardened, split, or perished original tube.
Key Features:
- Genuine Honda OEM part for assured compatibility and fit
- Maintains correct crankcase ventilation to reduce pressure build-up
- Flexible, pre-formed rubber hose for accurate routing and a neat install
- Oil, fuel vapour, and heat resistant for long service life
- Snug push-fit ends help provide a reliable, leak-resistant seal
- Helps minimise oil misting and keeps running performance consistent
- Direct replacement; no modifications required on listed models
- Suitable for routine maintenance when the original tube shows cracking or stiffness
Typical Applications:
Used on Honda-powered walk-behind lawnmowers and compatible garden machinery fitted with GCV160, GCV190, GSV160 and GSV190 engines. Ideal for restoring proper engine breathing after the original hose becomes brittle, cracked, or loose, helping maintain smooth running during domestic lawn care and commercial grounds maintenance.
