Description
Overview:
The Tube-Breather (Briggs & Stratton 846565) is a genuine OEM hose designed to manage crankcase breathing on Briggs & Stratton petrol engines. Built from fuel- and oil‐resistant materials for durability, it routes crankcase vapour to the intake path to balance internal pressure and minimise oil mist. Correct ventilation supports smooth running, helps protect seals, and maintains stable performance under load. This direct replacement matches the original shape and connection points for a secure, leak‐resistant fit on compatible Briggs & Stratton engines used across garden and light construction equipment, including walk‐behind lawn mowers, generators, pressure washers, tillers, and compactors. Ideal for routine servicing when the original tube has hardened, cracked, or become blocked, it restores proper engine breathing with straightforward fitting. As a genuine Briggs & Stratton part, 846565 offers reliable compatibility and long service life for professional and DIY users.
