Description
Overview:
This Cylinder Head Gasket is a Genuine Honda part designed to restore and maintain correct sealing between the cylinder head and engine block on small petrol engines. Manufactured to Honda's OEM standards for durability and heat resistance, it helps maintain compression and prevents combustion gas and oil leaks. It is tailored for the Honda GX200 and F720, ensuring a precise fit that supports smooth running, reliable starting, and consistent power output. By using the correct gasket, you reduce the risk of blow-by, misfires, and performance loss after head removal or top-end work. OEM reference 12251-ZL0-003 confirms compatibility and fitment, making it a dependable choice for routine maintenance or full overhauls where a fresh, exact-spec seal is essential.
Key Features:
- Genuine Honda OEM gasket for assured quality and compatibility
- Exact-fit design to suit the GX200 family for reliable sealing performance
- Maintains combustion pressure to protect power, efficiency, and starting
- Helps prevent air/fuel leakage and oil seepage at the head joint
- Built to withstand engine heat cycles, vibration, and petrol exposure
- Direct replacement part; straightforward to fit with standard workshop tools
- Ideal after head removal, decarbonising, valve work, or piston/ring service
- Supports engine longevity by reducing the risk of head-gasket failure
Typical Applications:
Used during engine rebuilds, head refits, or repairs on Honda GX200-based equipment such as generators, water pumps, pressure washers, plate compactors, cement mixers, and tillers (including F720). Suitable when addressing loss of compression, visible gasket damage, oil contamination at the head joint, or after overheating incidents. A fresh OEM gasket helps restore reliable sealing, stable idle, and consistent performance in everyday site, garden, and workshop environments.
Also known as:
Head gasket, cylinder head seal, engine head gasket, combustion gasket, top-end gasket, cylinder gasket, head-to-block gasket.
