The Husqvarna 543045577 Hose 7mm Id X 9mm Od Bulk is a genuine OEM replacement hose designed for the FS309 floor saw. As a direct OEM component, it is manufactured to Husqvarna's exact dimensional and material specifications, ensuring a proper connection within the machine's fluid or fuel routing system. DHS Equipment supplies this part to help keep your FS309 running at full capacity.
Key Features
- OEM-Grade Hose Construction — Built to Husqvarna's exact inner and outer diameter tolerances (7mm ID × 9mm OD), ensuring correct flow rate and secure sealing at connection points.
- Exact Dimensional Fit — Matches the original hose routing and connection specifications on the FS309, allowing straightforward installation without modification to fittings or mounts.
- FS309 Floor Saw Compatibility — Engineered specifically for the FS309 floor saw; cross-reference part number 543045577 against your parts diagram to confirm correct placement before installation.
- Consistent Fluid Delivery — A correctly functioning hose maintains steady, uninterrupted fluid transfer within the saw's system; a cracked or degraded hose can cause leaks, pressure loss, or contamination that affects cutting performance.
- Fuel and Fluid System Integrity — Using a genuine OEM hose with the correct wall thickness and material grade helps prevent premature deterioration from heat, vibration, and chemical exposure common in floor saw operation.
This hose serves as a fluid or fuel routing component within the FS309 floor saw, channeling liquid between system connections while maintaining a leak-free seal under operating pressure and temperature. The specific 7mm inner diameter and 9mm outer diameter dimensions are critical — a hose that is too loose or too tight at either connection point can result in leaks, restricted flow, or fitting damage. When the hose cracks, swells, or softens with age, it compromises the integrity of the entire fluid circuit, making timely replacement essential to sustained machine performance.
