Description
Overview:
The Spacer Flange for Stihl SR430 and SR450 (OEM 4244 120 2300) is a genuine Stihl intake component used in backpack blowers and mistblowers. It is a hard-wearing, heat‐resistant polymer insert that sits between the carburettor and the engine intake to set the correct spacing, support the carb body, and help maintain a reliable seal. By stabilising the intake connection, it reduces the risk of air leaks that can lead to poor running, hard starting, or erratic idle. Built for regular outdoor work, this spacer flange is designed for a precise fit on Stihl machines such as the SR430 and SR450 to keep performance consistent and minimise downtime. Genuine Stihl part for assured compatibility and long service life.
