Description
Overview:
The Inlet Pipe for Husqvarna 435 and 440 chainsaws (OEM No. 504 20 12-01) is a genuine Husqvarna component that links the carburettor to the engine intake, keeping the fuel/air path sealed and stable. Made from fuel‐resistant elastomer designed to tolerate heat, vibration and petrol/oil exposure, it helps prevent air leaks that cause hard starting, high idle, or lean running. Fitted to lightweight domestic and professional chainsaws, it restores consistent performance and reliability in regular cutting, pruning and firewood work. As a direct replacement, it is shaped for an accurate fit within the saw's intake assembly, supporting smooth throttle response and dependable power delivery on Husqvarna 435 and 440 models.
