Multiquip 66519 Hydraulic Hose Kit with 90 Degree 3/8 x 360mm

The Multiquip 66519 Hydraulic Hose Kit with 90 Degree 3/8 x 360mm is a genuine OEM component designed for Multiquip RAMMAX roller models including the RW1404MR, RW1504HF, and P33/24 HHMR-BD. Sourced directly from Multiquip, this kit ensures correct hose routing, connection angle, and length for a drop-in installation with no improvised adaptations. It is engineered to match the original hydraulic circuit layout on compatible roller models, maintaining proper flow paths and pressure integrity throughout the system. If you are servicing an RW1404MR, RW1504HF up to S/N, or a P33/24 HHMR-BD equipped with a blade, part number 66519 is the verified OEM replacement.

Key Features

• OEM-Matched Hose Assembly — Built to the exact 90-degree fitting angle and 360mm length specified for the original hydraulic circuit, ensuring correct pressure rating and connection integrity.
• Direct-Fit Installation — The 90-degree end fitting and pre-set hose length align with existing hydraulic ports on compatible RAMMAX rollers, allowing straightforward installation without modification to fittings or lines.
• Confirmed Fitment for RAMMAX Roller Models — Compatible with the RW1404MR (S/N 326075 and up and all serial ranges), RW1504HF (up to S/N 1534188), and P33/24 HHMR-BD with blade.
• Hydraulic Circuit Integrity — A correctly sized and properly angled hose maintains consistent fluid flow to the roller's hydraulic drive and blade systems, preventing pressure drop, heat buildup, and erratic machine response.
• Leak Prevention at High-Stress Connection Points — Hydraulic hose kits with angled fittings are particularly prone to failure at the bend when non-OEM substitutes are used; the 66519 is built to handle the mechanical stress at that 90-degree junction.

The hydraulic hose kit is a critical link in the roller's hydraulic circuit, routing pressurized fluid between components such as the drive motor, control valve, and blade assembly. The 90-degree fitting allows the hose to change direction within tight machine compartments without kinking or straining the line. When a hydraulic hose develops a leak, cracks at the fitting, or collapses internally, the machine can lose drive force, exhibit sluggish or uneven blade response, or shut down entirely due to low hydraulic pressure — interrupting compaction work and risking further damage to downstream components. Replacing a worn or failed hose with the correct OEM part like the Multiquip 66519 restores full hydraulic performance and protects the integrity of the entire circuit.
