The Wacker Neuson is a genuine OEM Threaded Plug designed for the RD27-100 and RD27-120 hydrostatic vibratory rollers, including standard and traction control configurations. As a direct factory replacement, this plug is produced to the same specifications as the original component fitted at the time of manufacture. Confirmed fitment spans multiple serial number ranges across the RD27 tandem roller series, making part number the correct choice for RD27-100 and RD27-120 machines in the field.
Key Features
- Genuine OEM Thread Integrity — Manufactured to Wacker Neuson's original thread pitch and dimensional spec, ensuring a pressure-tight seal without rework or chasing of threads.
- Drop-In Installation — Threads directly into the existing port on the RD27 roller, matching the original plug's engagement depth and seating surface for a straightforward swap.
- Broad RD27 Series Coverage — Fits RD27-100 and RD27-120 tandem vibratory rollers across standard and traction control variants, covering a wide range of serial number configurations.
- Hydraulic or Fluid System Integrity — A correctly seated threaded plug prevents fluid loss, contamination ingress, and pressure drop — keeping the roller's hydraulic and lubrication circuits performing as designed.
- Fuel and Fluid Safety Compliance — Proper sealing at threaded ports is critical on vibratory rollers; using the correct OEM plug eliminates the risk of leaks at service points or inspection ports.
A threaded plug is used to seal an open port in a hydraulic circuit, fluid reservoir, or drivetrain housing — blocking the passage when a fitting, sensor, or ancillary line is not in use. On the RD27 series tandem rollers, maintaining sealed ports is essential to keeping hydraulic pressure stable and preventing contamination from entering the system. A damaged, cross-threaded, or missing plug can lead to fluid leaks, pressure loss, and potential damage to pumps or motors downstream.
