Description
Overview:
The Piston Ring 40 mm for Stihl is a genuine OEM engine component designed to restore and maintain compression in 2‐stroke engines. Manufactured from high‐grade steel, it provides a reliable seal between the piston and cylinder wall, supporting clean starting, strong power delivery, and efficient running. This ring is sized precisely at 40 mm diameter (1.57 in) with a 1.5 mm width (0.06 in) to match original factory specifications, making it a direct replacement for worn or damaged rings. It suits a wide range of Stihl machines that use a 40 mm top end, including the MS 200 and MS 200 T. Ideal for top‐end refreshes and routine maintenance, it helps extend engine life by reducing blow‐by and maintaining stable compression. Genuine Part by Stihl. MPN: 1114 034 3001.
