Description
Overview:
This bellows is a Genuine Husqvarna OEM part designed for the air intake system on Husqvarna top-handle chainsaws, including the T540 XP and T540 XP II. Made from tough, flexible black elastomer (rubber), it forms a secure, airtight connection within the intake path to maintain correct airflow and sealing. By preventing unmetered air from entering the engine, it helps preserve smooth idling, clean acceleration, and reliable cutting performance. Built for the demands of professional arborists and maintenance users, it withstands vibration, temperature changes, and regular use. Supplied under Husqvarna's part number 515 99 73-01, it is an exact-fit replacement that restores factory performance when the original bellows has become cracked, hardened, or loose through age or fuel exposure.
