Stihl 11250343001 Piston Ring 1.2mm for MS360 BR350 BR430 BR450 SR430 SR450 

A 1.2mm piston ring is a critical component in the engine of a petrol chainsaw, mistblower, and electric starter blower. This thin, precision-engineered ring sits within the piston assembly, creating a seal between the piston and the cylinder wall. Its primary function is to maintain proper compression by preventing the leakage of fuel and exhaust gases, while also controlling the oil distribution on the cylinder walls. The 1.2mm thickness ensures a perfect balance of strength and flexibility, allowing the engine to run efficiently, reduce emissions, and extend the lifespan of the equipment. It is designed for high-performance engines, providing smooth operation and preventing wear.
