The Multiquip 57504 Swivel Fitting is a genuine OEM component designed for RAMMAX walk-behind roller models including RW1403HF, RW1404, RW1404MR, RW1504HF, RW1810, RW3010, and P33/24 series equipment. As a direct OEM replacement, part 57504 is produced to the same specification as the original, ensuring a correct fit within the hydraulic circuit without the need for modifications or custom adapters. DHS Equipment stocks this part to help you get your roller back in service with confidence in the component you are installing.
Key Features
- Genuine OEM Construction — Manufactured to the original Multiquip specification, delivering the correct thread form, sealing surface, and pressure rating for hydraulic integrity in roller applications.
- Rotational Swivel Design — Allows connected hydraulic lines to articulate freely, preventing hose twist and stress buildup at the fitting junction during roller operation.
- Broad RAMMAX Roller Compatibility — Confirmed fitment across RW1403HF, RW1404, RW1404MR, RW1504HF (up to S/N 1534188), RW1810, RW3010, and P33/24 series walk-behind rollers.
- Leak-Free Hydraulic Connection — A worn or damaged swivel fitting can cause hydraulic fluid loss, pressure drop, and loss of drive or vibration function; replacing it restores a sealed, pressure-tight circuit.
- Correct Part for the Application — Using part number 57504 ensures the fitting matches the port configuration and pressure rating specified for these roller models, protecting downstream hydraulic components.
A swivel fitting connects hydraulic lines within the roller's drive or vibration circuit while allowing the hose to rotate freely relative to the fitting body. This rotational capability prevents the hose from twisting under machine movement, which can cause premature hose wear, fatigue cracking, or connector failure. When a swivel fitting seizes, leaks, or fails, it disrupts hydraulic flow and pressure, which can result in loss of vibration output, reduced propulsion, or visible fluid leakage — all of which require the machine to be taken out of service until the fitting is replaced.
