Description
Overview:
This is a genuine Stihl flange (MPN: 4237 120 2202) for petrol hedge trimmers in the HS series. It is an intake flange that mounts between the carburettor and the cylinder to keep an air‐tight seal and correct alignment. Made from durable, heat‐resistant engineered polymer, it withstands vibration, fuel exposure, and repeated thermal cycles. By preventing air leaks, it helps maintain stable idle, smooth acceleration, and consistent cutting performance. Designed for a precise OEM fit on models such as HS 81 and HS 86, it is suitable for routine maintenance or a like‐for‐like replacement of a cracked or worn flange. As a genuine Stihl part, it supports long service life and reliable operation of your hedge trimmer.

Used when servicing the intake system, replacing a cracked insulator, or curing air leaks that cause erratic idle, hesitation, or poor fuel economy. Ideal during carburettor overhaul, after impact damage, or as preventative maintenance on Stihl HS‐series hedge trimmers operating in demanding, high‐vibration environments.
