Multiquip 66640 Hydraulic Hose 3/8" x 1305MM W/45-90

The Multiquip 66640 is a genuine OEM Hydraulic Hose 3/8" x 1305MM W/45-90 designed for the RW-1800 RAMMAX roller. As a direct OEM replacement, this hose is manufactured to match the original hydraulic routing and end-fitting angles — including the 45-degree and 90-degree terminations — ensuring correct installation without modification. If you're servicing an RW-1800 and need a hose that connects exactly as the original did, the part is the correct part for the job. DHS Equipment stocks genuine Multiquip OEM parts so you can get your machine back to work with confidence.

Key Features

• OEM-Grade Hydraulic Construction — Built to the same pressure rating and hose specification as the original, ensuring the hydraulic circuit on your RW-1800 operates within designed parameters.
• Pre-Formed 45° and 90° End Fittings — Dual-angle fittings are pre-installed at the correct orientations, allowing the hose to seat properly within the tight routing of the RW-1800 hydraulic system.
• Correct Length at 1305MM — Factory-specified 1305MM length ensures the hose reaches between connection points without stress, kinking, or slack that could cause premature wear.
• Direct Fit for RW-1800 RAMMAX Rollers — Verified fitment for the Multiquip RW-1800, a RAMMAX-series ride-on roller — no guesswork on compatibility.
• Hydraulic System Integrity — A damaged or degraded hose in this circuit can result in pressure loss, sluggish roller response, or hydraulic fluid leaks; replacing with the correct OEM hose restores full system performance.

A hydraulic hose is a pressurized fluid line that carries hydraulic oil between the pump, control valves, and actuators that drive the roller's movement and compaction functions. On the RW-1800, these hoses are routed through a compact chassis and must maintain a reliable, leak-free connection under continuous vibration and load. When a hose cracks, abrades, or develops a leak at the fitting, hydraulic pressure drops, which directly affects drive response and compaction force. Replacing a worn hose promptly with the correct OEM part keeps the hydraulic circuit sealed and operating at full efficiency.
