Description
Overview:
This O-Ring is a genuine Stihl sealing component for the MS400C and MS400C-M chainsaws. Supplied to OEM specification under number 1140 149 0400, it is designed to create a reliable seal in critical joints and housings within the machine, helping to prevent leaks and maintain stable operating pressure. The ring is made from a durable, oil- and fuel-resistant elastomer that withstands heat, vibration, and routine use in demanding cutting environments. As a direct-fit replacement, it supports correct assembly tolerances and long-term reliability. Whether you are a professional user or maintaining a saw at home, this OEM O-Ring helps keep your chainsaw performing as intended by Stihl and reduces the risk of downtime caused by seal failure.
Key Features:
- Genuine Stihl OEM part (1140 149 0400) for assured fit and compatibility
- Durable elastomer construction resists oils, fuels, and heat in typical chainsaw use
- Provides a tight seal to reduce leaks and maintain pressure integrity
- Direct replacement with correct cross-section and diameter for the specified location
- Helps preserve performance and reliability under vibration and load

- Suitable for preventative maintenance and repairs to minimise unplanned downtime
- Backed by Stihl's manufacturing standards for consistency
Typical Applications:
Used wherever Stihl specifies this O-Ring within the MS400C platform to seal interfaces that carry fluids or require pressure retention. Commonly installed during servicing to address age-related hardening or flattening of seals, or when reassembling components after inspection or replacement. Fit only in positions that call for OEM 1140 149 0400 to maintain correct clearances and sealing performance.
