The Multiquip 66404 Hydraulic Hose 3/8x290mm is a genuine OEM component designed for the RW-1403E RAMMAX walk-behind roller. This hose is manufactured to the exact bore diameter and length required for proper hydraulic circuit function on the RW-1403E, ensuring a direct, leak-free connection with no rework at the fittings. Sourced directly through Multiquip's OEM supply chain, the part delivers the same specification as the original part your machine left the factory with. If you're servicing or rebuilding the hydraulic system on your RW-1403E, this is the correct replacement hose.
Key Features
- OEM-Grade Hose Construction — Built to the correct pressure rating and inner diameter for the RW-1403E hydraulic circuit, maintaining consistent flow and system integrity.
- Exact Length and Diameter — At 3/8" bore and 290mm length, this hose routes and connects just as the original, allowing straightforward installation without cutting or adapting.
- Confirmed Fitment for RW-1403E — Verified for the Multiquip RAMMAX RW-1403E walk-behind roller; cross-reference part number 66404 before ordering to confirm application.
- Protects Hydraulic System Performance — A cracked or swollen hose causes pressure loss and erratic drive response; replacing with the correct OEM hose restores full hydraulic output and control.
- Genuine Multiquip OEM Part — Supplied as a genuine OEM replacement, this hose meets the same material and dimensional standards as the part originally installed on your machine.
A hydraulic hose carries pressurized fluid between the pump, control valves, and drive motors that power the roller's movement and vibration system. On a walk-behind roller like the RW-1403E, consistent hydraulic pressure is essential for smooth, controllable compaction passes — any leak or restriction in the hose directly affects drive response and compaction output. A hose that is cracked, abraded, or has deteriorated inner lining can cause pressure drop, erratic machine behavior, or complete loss of hydraulic function, making timely replacement critical to keeping the roller performing as intended.
