Description
Overview:
This genuine Stihl gasket (part number 4237 649 0302) is a flat sealing component used in petrol hedge trimmers such as the HS81R and HS81RC. It sits between mating surfaces to create an air‐tight and oil‐tight seal, helping to prevent leaks that can affect running and lubrication. Made from durable gasket material designed to cope with fuel, oil, heat and vibration, it supports reliable performance and long service life. As an OEM part, it provides the correct fit and sealing profile for the intended assemblies on Stihl HS series machines, making it a sound choice for routine maintenance or repairs. Using the correct gasket helps restore consistent starting, stable idling and clean acceleration by keeping the engine and related systems properly sealed.
