Description
Overview:
The Gasket for Stihl FR350 and FR450 (MPN 1123 129 0905) is a Genuine Stihl sealing component for petrol-powered handheld tools. Precision-cut from durable gasket material, it creates a tight seal between engine mating faces to prevent air and fuel leaks that can affect starting, idle quality, and power. Designed for the FR350 and FR450 and used widely across the Stihl range, this flat-profile gasket supports correct airflow and compression in small 2-stroke engines. It is suitable for routine servicing and repairs where gaskets must be renewed after disassembly. As a like-for-like replacement, it installs cleanly with no modification and helps maintain reliability over long service intervals.
Key Features:
- Genuine Stihl part (1123 129 0905) for assured compatibility and fit
- Durable construction to withstand engine heat, vibration, and regular use
- Accurate hole pattern for straightforward alignment and tidy installation
- Helps prevent vacuum and fuel leaks for stable running and performance
- Supports correct compression and fuel-air mixture for efficient operation
- Suitable for a wide range of Stihl machines for simplified spares stocking
- Ideal to replace whenever the joint is opened during maintenance
- Cost-effective way to reduce downtime and avoid repeat tear-downs
Typical Applications:
Used at engine and intake interfaces on compatible Stihl equipment, including brushcutters, clearing saws, chainsaws, blowers, mistblowers, hedge trimmers, pole pruners, drills, KombiSystem tools, and cut-off saws. Fit a new gasket after carburettor or manifold removal, when tracing vacuum leaks, or during scheduled overhauls to restore a reliable seal and consistent running.
