The Multiquip 66409 is a genuine OEM Hydraulic Hose 3/8 x 840mm designed for the RW1404MR RAMMAX walk-behind roller. Sourced directly from Multiquip, this hose meets the exact pressure ratings, diameter, and end-fitting specifications required by the original hydraulic circuit. It is confirmed for fitment on RW1404MR units, including serial number 326075 and up. When it comes to hydraulic lines, using the correct OEM component is critical — an improperly rated hose can compromise system pressure and lead to costly hydraulic failure on the job.
Key Features
- OEM-Rated Hydraulic Integrity — Manufactured to the same pressure tolerance and inner diameter as the original hose, ensuring the hydraulic circuit maintains consistent flow and pressure output.
- Exact-Length Replacement — At 840mm, this hose matches the original routing path in the RW1404MR hydraulic system, allowing direct installation without cutting or adapting line length.
- Confirmed RW1404MR Fitment — Verified for RW1404MR rollers, including the serial number 326075 and up production run, so you can order with confidence.
- Sustained Drum Drive Performance — A fully functional hydraulic hose keeps drum drive pressure steady, ensuring consistent compaction force and smooth roller operation across the full working cycle.
- Leak-Resistant Construction — Genuine OEM hose assembly is built to resist abrasion and hydraulic fluid degradation, reducing the risk of seepage or pressure drop that can affect machine control and output.
The hydraulic hose in a walk-behind roller like the RW1404MR carries pressurized fluid between the hydraulic pump and the drum drive or steering components, enabling the machine to deliver controlled compaction force and directional movement. A hose that is cracked, kinked, or worn through can cause a sudden loss of hydraulic pressure, resulting in reduced drum engagement, erratic steering, or a complete loss of drive function. Replacing a degraded hose promptly with a correctly rated OEM component keeps the hydraulic system operating at its designed pressure and protects downstream components such as pumps, motors, and control valves from stress caused by pressure fluctuation.
