Description
Overview:
The Active Sponge Washer is a Husqvarna OEM sealing washer designed for small-engine equipment and handheld tools. Made from durable sponge/foam material, it compresses to create a reliable seal between mating parts, helping to keep out dust and moisture while limiting minor leaks. This washer supports correct assembly clearances and can reduce vibration and rattle in covers and housings. It is suitable for a wide range of Husqvarna machinery commonly found in garden and construction settings, such as chainsaws and brushcutters. Identified by MPN 506 21 23 01, it is a direct replacement for a worn or deteriorated washer during routine servicing, helping maintain performance and prolong the life of adjacent components.
Key Features:
