The Multiquip 57422 Hydraulic Fitting RW-1800 P35K 2B 4B is a genuine OEM component designed for the P35K and RW-1800 series RAMMAX ride-on rollers, including 2B and 4B size variants. As an authorized Multiquip OEM part, the part is manufactured to the same specifications as the original fitting, ensuring a correct, leak-free connection within the hydraulic circuit. Confirm your model code against P35K or RW-1800 before ordering to ensure full compatibility with your machine's hydraulic plumbing configuration.
Key Features
- OEM Hydraulic Integrity — Manufactured to Multiquip's original thread form and port geometry, maintaining rated hydraulic pressure without seepage or fitting failures common with non-spec alternatives.
- Direct-Connect Replacement — Matches the original fitting's thread type, size, and port orientation so it seats and torques correctly into the hydraulic line without modification to hoses or fittings.
- Multi-Variant Coverage — Confirmed fitment for P35K (2B and 4B size variants) and RW-1800 RAMMAX ride-on rollers, covering a broad range of machines within these roller families.
- Hydraulic System Performance — A correctly functioning hydraulic fitting maintains consistent fluid flow and pressure to the roller's drive and vibration systems; a worn, cracked, or incorrectly sized fitting can cause pressure loss, erratic machine response, or hydraulic fluid leaks.
- Fluid System Safety — Hydraulic fittings operating under pressure demand correct spec parts; using the OEM 57422 reduces the risk of fitting blow-out or uncontrolled fluid loss during operation.
A hydraulic fitting serves as the sealed connection point between hydraulic hoses, lines, and components within the machine's fluid power circuit. On ride-on rollers like the P35K and RW-1800, hydraulic pressure drives critical functions including propulsion and vibratory drum operation, so every fitting in the circuit must hold a reliable seal under sustained working pressure. When a fitting corrodes, cracks, or develops thread damage, it can introduce air into the system or allow fluid to escape, leading to loss of drive response, overheating, or hydraulic system damage if not addressed promptly.
