Description
Overview:
This genuine Stihl piston ring is a replacement sealing ring for small two-stroke engines used in handheld tools such as brushcutters and trimmers. Built from a wear‐resistant metal alloy and precision‐finished, it restores and maintains cylinder compression, reduces blow‐by, and supports efficient heat transfer from the piston to the cylinder wall. Correct sealing helps engines start reliably, hold power, and run cleaner. Sized at 34 mm diameter (approx. 1.34 inches) with a 1.5 mm thickness (approx. 0.06 inches), it is suitable for selected Stihl machines including the FS81 and FS86. As an original OEM part (4126 034 3000), it offers a direct, like‐for‐like fit for the specified applications and supports long service life when installed and run‐in correctly.
