Description
Overview:
This is a genuine Husqvarna O-Ring designed for select professional and domestic chainsaws, including the 362 and 365 models. It is a circular sealing ring made from durable, oil- and fuel-resistant black rubber, sized by Husqvarna to suit the specific joint it serves on these machines. The O-Ring's job is to create a tight, elastic seal between mating parts so oil, fuel, and air cannot leak, helping the saw run cleanly and efficiently. Using the correct genuine O-Ring helps maintain system pressure, prevents drips, and reduces the risk of air ingress that can affect tuning and performance. It is a direct replacement for the original factory-fitted seal on compatible Husqvarna chainsaws and is suitable for regular service or repair work where this part number is specified.
Key Features:
- Genuine Husqvarna part for assured compatibility and reliability
- Robust elastomer construction resists petrol, chain oil, and common workshop chemicals
- Provides a secure seal to prevent oil/fuel leaks and unwanted air ingress
- Helps maintain correct system pressure and stable carburettor settings
- Supports efficient lubrication and cleaner operation with less mess
- Designed for the specific application on listed Husqvarna chainsaws
- Straightforward like-for-like replacement with no modifications required
- Long service life when installed on clean, undamaged mating surfaces
Typical Applications:
Used wherever this Husqvarna O-Ring is specified on the 36x/37x series saws, typically within oil or fuel circuits, pump housings, pipe unions, and casing interfaces. Ideal during routine servicing, leak tracing, or component replacement to restore sealing integrity, reduce oil/fuel seepage, and protect internal parts from contamination. Suitable for professional forestry, landscaping, and DIY maintenance on compatible models.
