Description
Overview:
The Rocker Gasket for Honda GX22 Engines (manufacturer part number 12312 ZM3 020) is a genuine Honda seal that sits between the rocker cover and the cylinder head. Made from durable, oil‐resistant gasket material, it maintains a tight seal to prevent oil leaks and keep contaminants out of the valve train area. This helps protect engine performance and reduces mess around the top end. Designed specifically for Honda's compact 4‐stroke engines, it offers a precise fit on GX22 and GX31 units commonly found in handheld and light machinery such as brushcutters, hedge trimmers, small tillers, and pumps. As an OEM component, it matches original specifications for thickness, profile, and resilience, supporting reliable operation after routine servicing or repair work.
