Description
Overview:
This is a genuine Stihl gasket (part number 4180 129 0903) for sealing critical joints on a wide range of Stihl handheld machines. Made from a durable, heat- and fuel-resistant composite material, it creates an airtight seal between mating engine components to prevent air, fuel or oil leaks. A sound seal helps maintain correct mixture, vacuum and compression, which supports easy starting, steady idling and reliable power under load. It is suitable for Stihl hedgetrimmers and multi-tools, including the HL100 and HL90K, and is also used across selected brushcutters, blowers, pole pruners and Kombi engines built on the same engine family. As an OEM gasket, it matches the original profile and port layout for consistent performance and a straightforward replacement.
