The Multiquip 66403 is a genuine OEM Hydraulic Hose 3/8x295mm designed for the RW-1403 RAMMAX roller. As a direct OEM replacement, this hose is manufactured to the exact pressure rating, bore diameter, and end-fitting specification required by the RW-1403 hydraulic system — no guesswork on compatibility. Sourced directly through authorized Multiquip distribution, the part ensures a correct, leak-free installation the first time. DHS Equipment stocks this part ready to ship so you can get your roller back in service fast.
Key Features
- OEM-Spec Pressure Rating — Built to the exact burst and working-pressure requirements of the RW-1403 hydraulic circuit, maintaining full system integrity under load.
- Correct Hose Dimensions — 3/8-inch bore and 295 mm length match the original routing and end-fitting positions on the RW-1403, allowing straightforward installation without cutting or adapting.
- Confirmed RW-1403 Fitment — Verified genuine OEM part for the Multiquip RW-1403 RAMMAX walk-behind roller; cross-reference part number 66403 before ordering to confirm application.
- Leak-Free Hydraulic Performance — A deteriorated or cracked hydraulic hose causes pressure loss, slow or unresponsive drum drive, and potential fluid contamination; replacing with the correct OEM hose restores full hydraulic output.
- Genuine Multiquip OEM Part — Supplied through authorized Multiquip distribution channels, ensuring you receive the same hose assembly installed at the factory — not a generic substitute.
A hydraulic hose transfers pressurized fluid between the pump, control valves, and drive components that power the RW-1403 roller's drum and travel functions. The hose must maintain a consistent seal under repeated pressure cycles and exposure to heat and vibration. When a hydraulic hose begins to crack, blister, or leak at its fittings, system pressure drops and the roller loses drive response or drum compaction force — catching and replacing a worn hose early prevents more costly hydraulic component damage downstream.
