STIHL Piston ring 44.7x1.2mm 11410343000 / 1141 034 3000

Overview:
The Piston Ring 44.7 x 1.2 mm is a genuine Stihl OEM component designed to maintain correct cylinder compression in two-stroke engines. Made from high-quality metal and machined to tight tolerances, it provides a reliable seal between the piston and cylinder wall to support clean combustion, steady power, and easier starting. With dimensions of 44.7 mm diameter and 1.2 mm thickness, it is engineered for the piston used in popular chainsaws such as the Stihl MS 261 and MS 261 C, as well as selected professional clearing saws. Replacing a worn or broken ring helps recover performance, reduce blow-by, and minimise smoke, prolonging the service life of your equipment. This genuine part fits directly in place of the original during routine maintenance or an engine top-end rebuild.
