Description
Overview:
This Genuine Stihl cylinder gasket is a precision-cut seal for two‐stroke engines used in handheld outdoor power tools. Made from durable compressed fibre composite, it sits between the cylinder and crankcase to maintain an airtight, fuel‐tight seal, protecting compression and preventing air or oil leaks that can cause poor running. Designed to meet Stihl OEM specifications, it provides a factory‐fit solution for servicing or rebuilding engines on popular models such as the BG45 and BG85. Supplied as a Genuine Part (MPN 4140‐029‐2300 / 41400292300), it supports reliable starting, steady idle and full power under load across a wide range of Stihl blowers, brushcutters, trimmers, hedge trimmers, drills and multi‐tools.
