Description
Overview:
This Cylinder Head Gasket is a Genuine Honda part for the GX390 series, OEM reference 12251-ZF6-W00. It is a flat, single-piece metal gasket with a reinforced fire ring around the cylinder bore to maintain a tight combustion seal. Designed to sit between the cylinder head and engine block, it prevents loss of compression and helps stop oil seepage at the top end. The durable construction withstands heat cycling and vibration common in hardworking 4‐stroke engines. It is a precise fit for Honda GX390 and GX390K1 engines used across site equipment, generators, pressure washers, compactors, and other plant and garden machinery. Use it when replacing a worn gasket or whenever the head is removed during routine service or a top-end rebuild.
