Description
Overview:
This Genuine Husqvarna gasket is a precision-cut sealing component for small two-stroke machines such as chainsaws and brushcutters. Made from oil-, fuel- and heat-resistant compressed fibre material, it sits between flat mating surfaces to create an airtight and fluid-tight seal, helping to maintain correct compression and prevent unwanted air or fluid leaks. Designed for a reliable OEM fit, it is suitable for Husqvarna chainsaws including the 242 and 254, as well as several related models in the same engine family. As a Genuine Part (MPN 501 86 21-02 / 501862102), it is a direct replacement for the original gasket supplied with the machine, supporting smooth running, easy starting, and consistent performance after service or rebuild work.
Key Features:
- Genuine Husqvarna OEM part for assured compatibility and quality
- Compressed fibre construction resists petrol, oil and operating temperatures
- Precision profile with accurate bolt holes and ports for a clean fit
- Provides a secure seal to reduce air leaks and fluid seepage
- Helps restore performance, idle stability and starting reliability
- Suitable for routine servicing, rebuilds and leak repairs
- Direct replacement with no modification required when used on listed models
- Supports engine integrity, reducing the risk of premature wear
- Consistent sealing helps maintain correct mixture and power output
- Durable material for long service life under typical use
Typical Applications:
Used during maintenance or overhauls when engine or housing joints are opened, such as refitting covers or cases on two-stroke Husqvarna power units. Ideal when replacing a worn or damaged gasket to cure vacuum leaks, oil misting or fuel seepage. Common in repairs to restore proper running after disassembly for cleaning, inspection, or part replacement.
