The Wacker Neuson Hydraulic Fitting is a genuine OEM component designed for the RD12 and RD12A series tandem rollers and the RT560 and RT820 series vibratory trench rollers. As a direct OEM part, is manufactured to the same specifications as the original fitting installed at the factory, ensuring a correct, leak-free connection within the hydraulic circuit. This fitting is confirmed compatible across multiple configurations of the RD12, RD12A, RT560, RT820, and RT820HT, as well as the RD11A and RD11AEC hydrostatic double drum vibratory rollers.
Key Features
- OEM-Grade Hydraulic Sealing: — Manufactured to exact thread form and sealing surface tolerances, maintaining rated hydraulic pressure without weeping or leaks under working conditions.
- Drop-In Compatibility: — Matches the original port geometry and thread specification, connecting directly into the existing hydraulic lines without modification to fittings or hoses.
- Broad Fitment Coverage: — Verified for RD12, RD12A, RD11A, and RD11AEC tandem rollers, plus RT560, RT820, and RT820HT vibratory trench rollers across solid and foldable ROPS configurations.
- Hydraulic System Integrity: — A correctly seated hydraulic fitting keeps drive, vibration, and steering circuits pressurized at spec; a worn or damaged fitting can cause pressure loss that degrades compaction performance and machine responsiveness.
- Fuel and Fluid System Safety: — Hydraulic fittings carry high-pressure fluid; using a correctly rated OEM fitting reduces the risk of fitting failure, fluid spray, and associated hazards on the worksite.
A hydraulic fitting serves as a sealed connection point within the machine's hydraulic circuit, linking hoses, tubes, and components such as pumps, motors, and control valves. In compaction equipment like tandem rollers and trench rollers, the hydraulic system drives propulsion, drum vibration, and steering — so every fitting in the circuit must hold pressure consistently. When a fitting cracks, strips, or develops a leak, hydraulic pressure drops, which can cause sluggish or uneven drum drive, loss of vibration amplitude, or reduced steering authority. Replacing a failed fitting promptly with the correct OEM part restores full circuit integrity and keeps the machine performing as intended.
