Description
Overview:
This Sleeve for Stihl chainsaws is a Genuine Stihl part designed for the intake system on selected models, including MS 181 and MS 181 C. It is a black, fuel- and heat‐resistant elastomer (rubber) sleeve that links and seals the carburettor to the engine intake, helping to prevent air leaks while isolating vibration. By maintaining an airtight connection, it supports reliable starting, stable idling, and consistent cutting performance. Built for everyday use in domestic and professional settings, it replaces worn, cracked, or hardened sleeves that can lead to erratic running or lean conditions. Supplied to original equipment specification under MPN 1139 141 1801, it offers a precise fit and dependable service life across the compatible Stihl 1139 series platforms.
Key Features:
- Genuine Stihl part for assured fit, compatibility, and build quality
- Robust elastomer resists petrol, oil, ozone, and engine heat for long service life
- Precision moulding provides an airtight seal to maintain correct air-fuel mixture
- Helps restore smooth starting, clean idling, and responsive acceleration
- Dampens vibration between engine and carburettor to reduce stress on components
- Direct replacement with OEM dimensions-no modifications required
- Suitable for routine maintenance or refurbishment of hard‐worked saws
- Supports overall fuel efficiency and cutting performance by preventing intake leaks
Typical Applications:
Used during scheduled maintenance, carburettor servicing, or engine rebuilds on compatible Stihl chainsaws. Ideal when symptoms include rough idle, difficult starting, poor throttle response, or visible cracking/perishing of the original intake sleeve. Suitable for professional arborists, landscapers, and DIY owners maintaining reliable saw operation.
