Description
Overview:
This muffler/exhaust gasket is a genuine Stihl replacement part for sealing the joint between the cylinder and the silencer on a range of Stihl machines, including the HT 250 pole pruner and FS 120 brushcutter. Supplied under MPN 4134 149 0600, it is made from a heat‐resistant gasket material suitable for high exhaust temperatures and vibration. The gasket helps prevent exhaust leaks, blow‐by, and loss of performance by maintaining a tight seal at the exhaust outlet. Its flat profile and precise cut-outs match the original fitment, supporting reliable assembly and correct alignment. Suitable for routine maintenance or repair where the original gasket has been disturbed, worn, or damaged. Brand: Stihl. Genuine Part (OEM) for assured compatibility and quality.
