The Wacker Neuson 5200016126 is a genuine OEM Hydraulic Cap designed for the RD27-100 and RD27-120 series tandem rollers, including Pro, Basic, and T4F configurations. As a direct OEM replacement, this cap is produced to the same specifications as the original component installed at the factory, ensuring proper sealing and system integrity across the full range of RD27 machines it covers. Contractors who rely on these ride-on tandem rollers for asphalt and soil compaction can trust that part number 5200016126 will fit and perform exactly as intended. Keep a spare on hand to avoid unexpected hydraulic system exposure during demanding compaction work.
Key Features
- OEM Sealing Integrity — Manufactured to the same material and dimensional tolerances as the original cap, ensuring a proper pressure-rated seal on the hydraulic reservoir or port it covers.
- Drop-In Fitment for RD27 Series — Engineered to thread or seat directly onto RD27-series hydraulic fittings with no adaptation, covering both the RD27-100 and RD27-120 model variants.
- Broad RD27 Coverage — Confirmed fitment across RD27-100 and RD27-120 machines, including Pro, Basic, T4F, and Hydrostatic Vibratory Roller configurations.
- Hydraulic System Protection — A correctly seated hydraulic cap prevents contamination, moisture ingress, and pressure loss that can degrade hydrostatic drive performance and accelerate component wear.
- Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson parts network, carrying the full part number 5200016126 for straightforward verification against your machine's parts manual.
A hydraulic cap serves as the primary closure point on a hydraulic reservoir or system port, preventing dirt, water, and debris from entering the hydraulic circuit. On ride-on tandem rollers like the RD27-100 and RD27-120, the hydrostatic drive system depends on clean, uncontaminated fluid to power the drums and propulsion — even minor contamination introduced through a missing or damaged cap can cause accelerated pump and motor wear, erratic drive response, or full system failure. Replacing a worn or missing hydraulic cap promptly is one of the simplest and most cost-effective ways to protect a machine's hydraulic investment.
