Description
Overview:
This radial seal is a genuine Husqvarna component for petrol chainsaws, designed to keep the engine sealed and running reliably. Made from a tough, oil- and fuel-resistant elastomer with a reinforced outer rim, it sits around a rotating shaft to prevent leaks and maintain correct crankcase pressure. This helps stable idling, smooth acceleration, and long service life of internal parts. Supplied as Husqvarna OEM No. 597 57 61-01, it offers an exact fit on popular pro and mid-range models such as the 346XP and 353. Built to Husqvarna's specifications, it is suitable for regular maintenance or full rebuilds where sealing performance is critical.
