The Multiquip 66644 Hydraulic Hose P35/RW1800 is a genuine OEM hydraulic hose designed for the RW-1800 RAMMAX roller. As a direct OEM replacement, 66644 is manufactured to the exact pressure ratings, fittings, and routing specifications required by the RW-1800 hydraulic system. Sourced through DHS Equipment as an authorized Multiquip parts distributor, this hose ships as the same component installed at the factory — no guesswork on sizing or connector type.
Key Features
- OEM-Grade Hydraulic Construction — Built to the precise pressure tolerances and hose diameter specs of the RW-1800 hydraulic circuit, ensuring consistent flow and resistance to pressure spikes.
- Drop-In Installation — End fittings match the original connection points on the RW-1800, allowing direct installation without adapters or rerouting.
- Confirmed RW-1800 Fitment — Engineered specifically for the RAMMAX RW-1800 roller; reference part number 66644 to verify compatibility before ordering.
- Maintains Full Hydraulic System Integrity — A worn or cracked hydraulic hose causes pressure loss, erratic roller behavior, and potential fluid contamination; replacing it with the correct OEM hose restores full hydraulic performance.
- Genuine Multiquip OEM Part — Supplied by an authorized Multiquip distributor, this hose meets the same material and construction standards as the original component.
A hydraulic hose carries pressurized fluid between the pump, control valves, and drive or vibration components of the roller. On the RW-1800, the hydraulic system is responsible for both propulsion and compaction force, so any degradation in hose integrity directly affects how the machine performs on the drum. A hose that is cracked, kinked, or worn through its outer layer can weep fluid, drop system pressure, and eventually fail entirely — leading to loss of drive or compaction function mid-job. Replacing a failing hose promptly with the correct OEM component keeps the hydraulic circuit sealed and operating at the pressures the system was designed around.
