Multiquip 66665 Hose 3/8" X 515MM W/90Deg

The Multiquip 66665 is a genuine OEM Hose 3/8" X 515MM W/90Deg designed for the RW1403HF RAMMAX walk-behind trench roller. As a direct OEM replacement, this hose is manufactured to the exact specifications required by the original equipment, ensuring a correct connection and consistent hydraulic or fluid routing within the machine. Sourced directly through Multiquip's authorized parts network, the part delivers the same fit and function as the original component it replaces. If you operate an RW1403HF, this is the correct hose to specify when servicing your roller.

Key Features

• Genuine OEM Construction — Built to the exact hose diameter, length, and 90-degree fitting angle specified for the RW1403HF, ensuring correct fluid routing without improvised connections.
• Correct 90-Degree End Configuration — The pre-formed 90-degree fitting seats flush at the connection port, allowing for clean installation in tight routing paths common to trench roller frames.
• Confirmed RW1403HF Fitment — Verified for the RAMMAX RW1403HF walk-behind trench roller; use part number 66665 to confirm compatibility when ordering.
• Specified Length and Diameter — At 515MM in length and 3/8" bore diameter, this hose matches the OEM routing path exactly, preventing stress on fittings and maintaining proper flow rate.
• Leak-Free System Integrity — A worn or incorrectly sized hose can cause fluid loss, pressure drop, or hydraulic system contamination; replacing with the OEM 66665 restores system integrity and protects downstream components.

This hose routes fluid between system components on the RW1403HF walk-behind trench roller, maintaining the pressure and flow required for consistent roller operation. The 90-degree end fitting allows the hose to navigate tight clearances within the machine's frame without kinking or stressing the connection points. When a hose of this type degrades, cracks, or develops a leak, it can cause fluid loss, reduced hydraulic performance, or contamination of the fluid circuit — making timely replacement with the correct OEM part essential to keeping the roller running at full capacity.
