The Wacker Neuson 5200022118 is a genuine OEM Hydraulic Fitting designed for the RD7 series walk-behind tandem rollers, covering the RD7, RD7A, RD7H, RD7He, and RD7Ye model variants. As a factory-original component, it is manufactured to the exact dimensions and thread specifications required by the hydraulic system in these machines, ensuring a leak-free connection without the need for adapters or modifications. Cross-reference your model number against the RD7A, RD7H, RD7He, and RD7Ye variants listed for this part to confirm compatibility before ordering. Keeping the hydraulic circuit sealed and flowing correctly is critical to drum drive performance on any walk-behind tandem roller, making this fitting a straightforward maintenance or repair item to have on hand.
Key Features
- OEM Thread and Port Dimensions — Manufactured to the exact thread form, port size, and sealing geometry specified for the RD7 series hydraulic system, so connections seat correctly on the first install.
- Direct-Fit Replacement — Seats directly into the existing hydraulic circuit port with no reworking of lines or fittings required, keeping repair time to a minimum.
- Broad RD7 Series Coverage — Compatible with RD7, RD7A, RD7H, RD7He, and RD7Ye tandem roller configurations, including North America-specific and walk-behind roller builds.
- Hydraulic Circuit Integrity — A correctly installed fitting maintains the closed-loop pressure needed for consistent drum drive and steering response; a failed or leaking fitting can cause erratic drum behavior or loss of hydraulic drive.
- Fuel and Fluid System Safety — Hydraulic fittings operating under pressure must meet precise sealing standards; using a genuine OEM fitting eliminates the risk of pressure-side leaks that can create fire or injection hazards on the jobsite.
A hydraulic fitting connects sections of hydraulic line or joins a hose to a component within the machine's closed-loop hydraulic circuit. On a walk-behind tandem roller like the RD7 series, the hydraulic system is responsible for driving the drums and, depending on the model, powering steering and vibration functions — meaning any fitting that leaks or fails under pressure can starve the circuit and bring work to a halt. Worn, cracked, or cross-threaded fittings allow fluid loss that drops system pressure, leads to sluggish or uneven drum response, and can introduce air into the circuit. Replacing a damaged fitting promptly with a correctly rated, properly threaded OEM part restores circuit integrity and protects the downstream hydraulic components from damage caused by running low on fluid or operating at reduced pressure.
