The Multiquip 66790 is a genuine OEM Hydraulic Hose (45 Degree/90 Degree) designed for the P33/24 HHMR-BD with Blade roller. As a factory-sourced component, this hose is manufactured to the exact routing geometry and pressure ratings required by the hydraulic circuit on these RAMMAX roller units. Confirmed fitment for the P33/24 HHMR-BD ensures the hose seats correctly with the pre-angled end fittings — no bending, re-routing, or adapting required. When you need a dependable hydraulic hose to get your roller back in service, Multiquip part 66790 is the correct replacement.
Key Features
- OEM-Specified Hose Construction — Built to the precise pressure rating, inner diameter, and hose material specified for the P33/24 HHMR-BD hydraulic system, so performance matches the original design intent.
- Pre-Angled 45-Degree and 90-Degree End Fittings — The dual-angle end fittings are configured to follow the original routing path exactly, allowing a straightforward swap at both connection points without fabrication or adapter fittings.
- Confirmed Fitment for P33/24 HHMR-BD — Verified for the P33/24 HHMR-BD with Blade RAMMAX roller, giving you confidence that this is the correct hose before it ships.
- Maintains Full Hydraulic System Pressure — A correctly seated, properly rated hose preserves hydraulic pressure throughout the circuit, keeping roller drive and blade functions responsive and consistent during compaction passes.
- Hydraulic Leak Prevention — A degraded or incorrect hose can cause pressure loss, fluid leaks, and potential hydraulic system damage; replacing it with the OEM part restores a sealed, pressure-stable circuit.
A hydraulic hose carries pressurized hydraulic fluid between the pump, control valves, and actuators that power the roller's drive and blade systems. When hose integrity is compromised — through cracking, abrasion wear, or fitting failure — hydraulic pressure drops, causing sluggish or unresponsive machine behavior and risking fluid contamination of surrounding components. Replacing a failed hose promptly with the correct OEM part restores the sealed, high-pressure circuit the roller depends on for consistent operation.
