Description
Overview:
This Cylinder Gasket is a Genuine Stihl OEM part designed for professional and domestic chainsaws. It seals the joint between the cylinder and crankcase to maintain airtight integrity, correct crankcase pulse, and stable compression. Made from heat-resistant, fuel- and oil-tolerant gasket material, it withstands the thermal and chemical stresses typical of two-stroke engines. Precision-cut for accurate alignment, it helps prevent air leaks that can cause lean running and premature wear. Purpose-built for Stihl models such as the 038 and MS380, it is a dependable choice during top-end servicing, piston replacement, or a full rebuild. Genuine status ensures the correct profile, port openings, and fastener holes for reliable fitment and performance.
