Description
Overview:
This Genuine Stihl piston ring is a precision replacement for the TS400 cut-off saw (also listed as TS 400). Made from durable, heat-treated steel, it restores and maintains correct cylinder sealing, helping the engine build and hold compression for easy starting, steady power, and efficient running. The ring measures 49 mm x 1.5 mm, matching the original bore and ring thickness for this model. Designed to withstand continuous high temperature and friction in a 2‐stroke engine, it supports clean combustion and reduces blow-by.
