The Wacker Neuson is a genuine OEM Seal Plug designed for the RD27-100 and RD27-120 hydrostatic vibratory rollers. As a factory-sourced component, it meets the exact dimensional and material specifications called out in the original equipment design. This part is confirmed to fit multiple machine configurations across both the RD27-100 and RD27-120 series, making it the straightforward choice when servicing these tandem rollers. Ordering by part number ensures you receive the correct plug without guesswork.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's original material and dimensional spec, so the plug seats and seals exactly as intended in the hydraulic or fluid passage it closes.
- Direct-Fit Installation — Engineered to the original thread pitch and diameter, this plug installs into the existing port without chasing threads or sourcing adapters.
- Confirmed RD27 Series Compatibility — Fits RD27-100 and RD27-120 hydrostatic vibratory roller configurations, covering multiple machine serial ranges within both model lines.
- Fluid Containment Where It Counts — A properly seated seal plug prevents fluid loss and contamination ingress at service ports and unused hydraulic passages, keeping system pressure stable during compaction operations.
- Hydraulic System Safety — An improperly sealed or missing plug in a hydraulic circuit can lead to pressure loss or contamination that compromises control response on a live roller — using the correct OEM plug eliminates that risk.
A seal plug closes off an unused or service port within the machine's hydraulic or fluid system, preventing leaks, pressure loss, and the entry of dirt or debris into the circuit. On hydrostatic vibratory rollers like the RD27 series, maintaining a sealed hydraulic system is critical to consistent drum drive response and smooth compaction performance. When a seal plug fails, cracks, or is lost during service, fluid can weep from the port and contaminants can enter the system, leading to degraded hydraulic performance and potential damage to downstream components.
