Description
Overview:
The Sealing Collar is a Genuine Husqvarna component designed to keep key joints in your chainsaw air‐ and oil‐tight. Built from a durable, fuel- and oil-resistant elastomer, it helps prevent leaks, contamination, and loss of performance caused by perished or worn seals. Engineered to the original specification, it provides a precise, secure fit on Husqvarna professional saws such as the 281 and 281XP. The part matches OEM No. 501 81 18-01 (MPN 501811801), so you can fit it with confidence during routine servicing or a full overhaul. A sound sealing collar supports reliable starting, stable running, and long component life, making it a sensible preventative replacement for both trade users and home mechanics who rely on consistent chainsaw performance.
Key Features:
- Genuine Husqvarna OEM part for assured compatibility and quality
- Precision fit to match the original seating surfaces and tolerances
- Durable elastomer construction resists petrol, chain oil, heat, and vibration
- Helps prevent air and fluid leaks that can affect performance and reliability

- Engineered for the Husqvarna 281/288 platform for dependable performance
- OEM No. 501 81 18-01 / MPN 501811801 for easy identification and ordering
