Description
Overview:
This Muffler/Exhaust Gasket is a Genuine Stihl part designed for petrol hedgetrimmers such as the HS72 and HS74. It sits between the cylinder exhaust port and the muffler, sealing the joint to stop gas leaks and maintain correct engine performance. Made from a heat‐resistant gasket material (graphite/fibre composite), it withstands high temperatures and vibration without breaking down. A precise cut-out and two-bolt flange pattern ensure proper alignment and a dependable seal. Using the correct genuine gasket helps protect the engine from hot gas blow‐by, keeps noise levels consistent, and preserves backpressure for smooth running. Manufacturer reference: 4226 149 0600 (also written as 42261490600).
