Description
Overview:
The O-Ring 25x3.5 is a genuine Stihl part designed to create a dependable seal in small engine assemblies and fluid connections. Made from durable rubber, it helps prevent fuel, oil, and air leaks, supporting reliable starting and smooth running. With a precise 25 mm inner diameter and 3.5 mm cross-section, it fits accurately into matching grooves without distortion. Suitable for a wide range of handheld Stihl tools, including grass trimmers and brushcutters, it is commonly used in models such as the FS40 and FS40C. Its robust construction is well suited to the vibration, heat, and fuel exposure found in outdoor power equipment, helping to maintain performance and reduce premature wear on surrounding components.
Key Features:
- Genuine Stihl OEM part for assured fit and performance
- Size: 25 mm inner diameter x 3.5 mm cross-section for accurate sealing
- Durable rubber compound for long service life in engine environments
- Helps prevent fuel, oil, and air leaks to maintain reliable operation
- Supports correct pressure retention in housings, caps, and line joints
- Resistant to vibration and temperature changes typical of handheld tools
- Consistent dimensions for repeatable installation and sealing integrity
- Simple to fit when replacing worn seals during routine maintenance
Typical Applications:
Used to seal static or lightly dynamic joints in small engines and attachments, such as fuel system connections, carburettor interfaces, pump or cover seals, and line unions. Ideal for trimmers, brushcutters, chainsaws, blowers, and kombi tools where a compact, reliable ring seal is required to stop leaks and maintain system efficiency.
