The Multiquip 57485 Hydraulic Fitting is a genuine OEM component designed for RAMMAX walk-behind roller models including the RW1404MR, RW1403HF, and RW1504HF. As a direct OEM replacement, part 57485 is manufactured to the same specifications as the original, ensuring a correct, leak-free connection within the hydraulic circuit. This fitting is confirmed compatible with RW1404MR units from S/N 326075 and up, RW1403HF rollers, and RW1504HF rollers up to S/N.
Key Features
- Genuine OEM Construction — Manufactured to original specifications with correct thread form, seat angle, and port sizing for a dependable, leak-free hydraulic connection.
- Direct-Install Replacement — Matches the original fitting profile, so it threads into the existing hydraulic port without rework or adaptation.
- Confirmed Fitment — Verified for RW1404MR (S/N 326075 and up), RW1403HF, and RW1504HF (up to S/N 1534188) RAMMAX walk-behind rollers.
- Hydraulic Integrity — A correctly seated fitting maintains system pressure and flow, keeping drum vibration and drive performance at spec. A damaged or leaking fitting can cause pressure loss and erratic roller operation.
- Pressure-System Safety — Proper hydraulic fittings are critical in pressurized circuits; using a correctly rated OEM fitting prevents joint failure under working pressure.
A hydraulic fitting serves as the connection point between hoses, lines, and hydraulic components within the roller's pressurized fluid circuit. It creates a sealed, threaded junction that allows hydraulic fluid to flow at operating pressure without leaking. When a fitting becomes cracked, cross-threaded, or corroded, the resulting fluid loss drops system pressure and can lead to sluggish or uncontrolled drum and drive behavior. Replacing a worn fitting promptly with the correct OEM part restores circuit integrity and keeps the roller operating as intended.
