Description
Overview:
The Piston Ring 49mm x 1.5 mm is a genuine Stihl engine component designed to restore and maintain compression in small petrol tools. Built from durable metal for long service life, it creates a tight seal between the piston and cylinder to reduce blow‐by, improve power, and support clean running. Sized at 49 mm (1.93 inches) outer diameter and 1.5 mm (0.06 inches) thickness, it is a direct replacement part for selected Stihl machines, including the TS350 and TS360 disc cutters. Ideal for routine servicing or rebuilds, it helps address symptoms such as hard starting, loss of power, and excessive exhaust smoke. OEM/MPN references include 1127 034 3007 and 11270343007 for accurate identification and ordering.
