Description
Overview:
This genuine Honda O Ring is a small but essential sealing component for Honda Mini 4‐Stroke engines, including the GX25T and related variants. Manufactured to Honda's OEM standards (MPN 91308-Z3E-000), it is made from a durable, fuel- and oil‐resistant elastomer designed to seal joints between engine parts and prevent leaks. A correct, tight seal helps maintain engine efficiency, stable idling, and reliable starting. Commonly used around assemblies such as carburettors, covers, and housings, it keeps fluids and vapours where they should be and stops contamination entering the system. Built for the demands of handheld and light machinery, this O Ring is ideal for brushcutters and trimmers powered by engines in the GX25 and GX35 family.
