Description
Overview:
The Gasket/Packing Head is a genuine Honda OEM part for GXV160H2 and GXV160UH2 engines commonly fitted to professional lawnmowers such as the HRH536 series. This thin, precision-cut metallic gasket sits between the cylinder head and engine block to form a reliable seal. By keeping combustion pressure contained and separating oil and coolant passages, it prevents leaks and helps the engine run smoothly and efficiently. Made to Honda's specifications for fit and durability, it restores correct sealing after head removal due to maintenance such as decarbonising, valve service, or head refurbishment. Using the correct head gasket is essential for maintaining compression, reducing emissions, and protecting the engine from damage caused by fluid cross-leaks or air ingress.

- Genuine Honda OEM part for assured compatibility and fit
- Reliable seal between cylinder head and block to maintain compression

Used during engine rebuilds, head replacement, or top-end servicing on Honda GXV160-powered lawnmowers and turf equipment. Ideal for restoring correct sealing after overheating incidents, carbon cleaning, valve work, or when resolving loss of compression, oil seepage, or coolant leaks. Suitable for commercial grounds care, landscaping, local authority maintenance, and demanding domestic use.
