The Multiquip 502302850 Oil Hose 3/8 320L is a genuine OEM hydraulic oil hose designed for MDR-9DYE, MDR-9D, and MDR-9GH ride-on power trowels. As a direct OEM replacement, this hose is manufactured to the exact diameter and length specifications required by the hydraulic system on these machines. Sourced directly through Multiquip's authorized parts network, the part ensures a correct, leak-free connection with no guesswork on fitment. DHS Equipment stocks this part to keep your trowel operating at full capacity.
Key Features
- OEM-Grade Hose Construction — Built to the exact 3/8-inch bore and 320mm length specification required by the MDR-9 series hydraulic circuit, maintaining proper oil flow and pressure integrity.
- Direct Hydraulic System Fit — Engineered as a drop-in replacement that connects directly to the existing hydraulic fittings on MDR-9DYE, MDR-9D, and MDR-9GH trowels without reworking lines or adapters.
- Confirmed Fitment — Verified for MDR-9DYE, MDR-9D, and MDR-9GH power trowels, so you can order with confidence using part number 502302850.
- Leak Prevention — A cracked or deteriorated oil hose causes hydraulic pressure loss and oil contamination that can disable blade pitch control and damage the hydraulic pump — replacing it promptly protects the entire system.
- Fuel System Safety Compliance — Hydraulic oil hoses that fail under pressure create slip hazards and fire risk on the worksite; using the correct OEM hose ensures the line holds rated pressure safely.
The oil hose routes hydraulic fluid between key components of the trowel's hydraulic system, maintaining the consistent pressure needed to control blade pitch and machine drive. When this hose cracks, softens, or develops a leak, hydraulic pressure drops and the operator loses responsive control over the trowel's blades — leading to uneven finishing and potential pump damage. Replacing a worn hose with the correct OEM part restores full hydraulic integrity and protects the downstream components it serves.
