Description
Overview:
This Valve Stem Seal is a genuine Honda part (12209-KT7-013) for the GX100 petrol engine. It controls lubricating oil at the valve guide, preventing oil from entering the combustion chamber and helping the engine run cleaner and more efficiently. The seal combines an oil‐resistant elastomer with a metal-reinforced body for stability under heat, plus a precision sealing lip to maintain reliable contact on the valve stem. Built to Honda's OEM dimensions, it provides a secure fit that resists vibration and wear. Suitable for small Honda equipment engines used in generators and compact machinery, including GX100-powered sets such as EU20i, it supports dependable starting, steady running, and reduced exhaust smoke over long service intervals. Genuine Honda quality ensures compatibility and consistent performance.
