Description
4229 358 7702 STIHL Hose – Genuine OEM Fan Housing Part
The STIHL Hose (4229 358 7702) is a genuine OEM internal component designed to support proper airflow and system routing inside the fan housing of many STIHL handheld blowers and shredder vac units. This hose plays an important role within the housing assembly by directing air flow or connecting internal passages required for reliable engine and blower performance.
Over time, internal hoses may crack, harden, split, or become disconnected due to vibration, heat exposure, fuel residue, or aging. A damaged hose can result in air leaks, reduced blower efficiency, inconsistent engine performance, or improper airflow inside the housing. Replacing it with the correct OEM part helps restore proper internal function without replacing the entire fan housing assembly.
Manufactured to STIHL factory specifications, this genuine hose ensures correct fitment, flexibility, and long-term durability under professional operating conditions.
