The Multiquip 66645 is a genuine OEM hydraulic hose 3/8" x 1380MM with 45-90 degree fittings designed for the RW-1800 RAMMAX ride-on roller. As a direct OEM replacement, this hose is manufactured to the exact pressure ratings, bend geometry, and end-fitting configuration specified for the RW-1800 hydraulic system. Sourced directly from Multiquip, 66645 ensures a correct, no-compromise installation in your machine's hydraulic circuit. DHS Equipment stocks this part to keep your roller back in service with confidence.
Key Features
- OEM-Rated Pressure Integrity — Built to the hydraulic pressure specifications of the RW-1800 system, ensuring the hose handles operating loads without risk of premature failure or weeping at the fittings.
- Pre-Configured 45-90 Degree End Fittings — The angled fittings are factory-set to match the routing geometry of the RW-1800 hydraulic circuit, allowing the hose to seat correctly without bending or stressing the line.
- Correct 1380MM Hose Length — Cut and crimped to the OEM-specified length so the hose reaches between connection points with proper slack — not too tight, not too loose.
- RW-1800 RAMMAX Roller Fitment — Confirmed fit for the RW-1800, a RAMMAX ride-on roller in the Multiquip compaction equipment lineup.
- Hydraulic System Safety — A worn, cracked, or incorrectly specified hydraulic hose poses a serious fluid injection and fire hazard. Using the correct OEM hose maintains safe system pressure containment and protects the operator.
A hydraulic hose is the pressurized conduit that carries hydraulic fluid between the pump, control valves, and actuators that drive and steer the roller. On the RW-1800, the hydraulic system controls both propulsion and drum functions, so a compromised hose can cause loss of drive, erratic steering, or a complete hydraulic failure on the job. A hose that is the wrong length, wrong angle, or wrong pressure rating can leak, abrade against the frame, or burst under load — making an exact OEM replacement the correct choice every time this component is serviced.
