The Wacker Neuson is a genuine OEM Threaded Plug 1/2-20 designed for the RD27-100 and RD27-120 series hydrostatic vibratory rollers, including standard and Traction Control configurations. As a genuine OEM component, is manufactured to the exact specification of the original part, ensuring a correct, secure fit in the threaded port it seals. This plug is a critical hardware item used across the full RD27 model family, covering all known machine configurations for both the RD27-100 and RD27-120 series.
Key Features
- Genuine OEM Thread Integrity — Manufactured to the exact 1/2-20 thread specification of the original, ensuring a leak-free seal without cross-threading risk.
- Direct Port Match — Threads directly into the designated port on RD27 series rollers with no rework or thread chasing required on a properly maintained fitting.
- Broad RD27 Series Coverage — Confirmed fitment across RD27-100 and RD27-120 rollers in standard and Traction Control configurations, spanning multiple build variants.
- Hydraulic or Fluid System Integrity — A correctly seated threaded plug prevents fluid loss from open ports, protecting the hydraulic or lubrication circuit from contamination and pressure drop.
- Corrosion-Resistant Hardware — Built to withstand the demanding environment of walk-behind roller operation, including exposure to moisture, debris, and mechanical vibration.
A threaded plug seals an unused or service-access port within a machine's fluid system — whether hydraulic, lubrication, or coolant-related. On the RD27 series hydrostatic vibratory rollers, maintaining sealed ports is essential to preserving system pressure and keeping contaminants out of sensitive circuits. A missing, damaged, or incorrect plug can lead to fluid leaks, pressure loss, or ingestion of debris, any of which can compromise roller performance or cause premature wear to internal components.
