Description
Overview:
The Piston Ring 46 x 1.5 mm (1.81 x 0.06 in) is a genuine Stihl replacement part designed to restore and maintain compression in small two-stroke engines. Built from durable materials and precision-engineered to factory tolerances, it helps seal the combustion chamber, reduce blow-by, and support efficient starting and power delivery. Ideal for Stihl handheld machinery, it is suitable for models such as the SR340 and SR420 that rely on consistent compression for dependable performance. This ring is a direct-fit OEM component for straightforward replacement when the original ring shows wear, scoring, or loss of tension.
