The Wacker Neuson is a genuine OEM Hydraulic Fitting 4-6 St. designed for RD7, RD16, and RD27 series tandem rollers. This fitting is sourced directly from Wacker Neuson, ensuring it meets the exact dimensional and pressure tolerances of the original hydraulic system. It is also confirmed to fit the CRT60-74L ride-on concrete trowel. Whether you are servicing a walk-behind RD7 or a ride-on RD27 Pro, the delivers a direct, verified replacement for the OEM fitting it replaces.
Key Features
- OEM Hydraulic Integrity — Manufactured to the exact thread form, port sizing, and pressure rating of the original fitting, ensuring no leakage or flow restriction in the hydraulic circuit.
- Direct Drop-In Installation — Matches the original hydraulic line connection points on supported machines, allowing straightforward installation without reworking hydraulic plumbing.
- Broad Tandem Roller Coverage — Verified fitment across the RD7, RD7H, RD16-90, RD16-100, RD27-100, and RD27-120 model families, as well as the CRT60-74L.
- Hydraulic System Continuity — A correctly seated fitting maintains consistent hydraulic pressure across the drive and vibration circuits — a failed or undersized fitting can cause pressure drop, erratic drum vibration, or loss of propulsion.
- Fuel and Fluid Safety Compliance — A properly rated hydraulic fitting prevents unintended fluid release under operating pressure, reducing fire and slip hazards on the worksite.
A hydraulic fitting is a threaded or compression connector that joins hydraulic hoses, tubes, or components within the machine's hydraulic circuit. In tandem rollers like the RD7 and RD27 series, the hydraulic system powers both propulsion and drum vibration, so every fitting in the circuit must hold a reliable, leak-free seal under continuous working pressure. When a fitting cracks, strips, or corrodes, hydraulic fluid loss leads to reduced drive force, inconsistent compaction output, and potential hydraulic system damage if left unaddressed.
