Multiquip 66639 Hydraulic Hose 1/2" x 1450MM W/45-45

The Multiquip 66639 is a genuine OEM Hydraulic Hose 1/2" x 1450MM W/45-45 designed for the RW-1800 RAMMAX roller. As a direct Multiquip OEM part, 66639 is manufactured to the exact pressure ratings, hose diameter, and fitting angles required by the RW-1800 hydraulic system. The pre-formed 45-degree fittings at both ends ensure correct routing and a leak-free connection without improvisation or adapter hardware. If you're servicing or rebuilding the hydraulic circuit on your RW-1800, this is the correct replacement hose to restore full system integrity.

Key Features

• OEM-Spec Hydraulic Construction — Built to the exact pressure capacity and inner diameter required by the RW-1800 hydraulic circuit, ensuring consistent flow and system pressure under operating loads.
• Pre-Configured 45-45 Fittings — Both ends arrive pre-fitted with 45-degree angled connectors that match the RW-1800's factory hose routing, eliminating the need for makeshift bends or transition fittings.
• Correct 1/2" x 1450MM Dimensions — The hose length and bore diameter are sized specifically for the RW-1800, so the replacement drops straight into the existing hydraulic line path.
• RW-1800 RAMMAX Roller Fitment — Confirmed fitment for the Multiquip RW-1800 walk-behind roller, a machine that relies on precise hydraulic performance for drum drive and steering response.
• Genuine Multiquip OEM Part — Sourced directly from Multiquip, part this part meets the same material and burst-strength standards as the hose installed at the factory, supporting long service intervals in demanding compaction applications.

A hydraulic hose is the pressurized conduit that transfers hydraulic fluid between the pump, control valves, and hydraulic motor or actuator on a roller. On the RW-1800, the hydraulic system controls drum drive, so a hose that is cracked, abraded, or leaking will cause a loss of drive pressure, sluggish or uneven drum rotation, and fluid contamination that can damage downstream components. Replacing a worn hose promptly with the correct OEM part restores full hydraulic pressure and protects the rest of the system from contamination-related wear.
