Description
Overview:
This is a genuine Husqvarna engine gasket designed to seal key joints within the powerhead on selected Husqvarna chainsaws. Manufactured from OEM-grade composite gasket material, it is made to withstand fuel, oil and engine heat, maintaining an airtight, fluid-tight seal between mating surfaces. By preserving compression and preventing air or oil leaks, it supports smooth starting, stable idling and reliable power. Engineered to Husqvarna factory dimensions for a precise fit on models including the 262XP and 257, it matches cut-outs and bolt holes for accurate alignment. Using the correct OEM No. 501 86 25-02 (MPN: 501862502) helps ensure compatibility and long-term performance. Suitable for routine servicing, top-end rebuilds or after splitting the crankcases, this genuine part supports lasting engine integrity.
