Description
Overview:
This genuine Stihl piston ring is a 38 x 1.5 mm component (approx. 1.50 x 0.06 in) designed to restore and maintain correct compression in two-stroke trimmers and brushcutters. It replaces the original ring in selected Stihl machines, including FS 120 and FS 120 R. Made from durable, wear-resistant ring material, it provides a reliable gas seal between the piston and cylinder wall, helping the engine start easily, deliver steady power, and run efficiently. Precision sizing ensures correct fit in the groove and stable operation at high RPM. As an OEM part (4119 034 3002), it matches factory specification for profile and tension, making it a dependable choice when refreshing a top end or replacing a worn or damaged ring.
