The Wacker Neuson Seal Plug is a genuine OEM component designed for the RD27-100 and RD27-120 Hydrostatic Vibratory Rollers. As a direct factory replacement, this seal plug maintains the integrity of fluid or pressure passages within the roller's hydraulic and drivetrain systems. Sourced directly through Wacker Neuson's OEM parts program, the is produced to the same specification as the part installed at the factory — ensuring a correct, reliable fit every time. Whether you're performing scheduled maintenance or addressing a leak, installing the correct OEM seal plug is the straightforward solution.
Key Features
- Genuine OEM Sealing Performance — Manufactured to exact material and dimensional spec, this seal plug maintains proper fluid containment and pressure retention in the hydraulic circuit where aftermarket substitutes may allow seepage or improper seating.
- Drop-In Replacement — Threads or seats directly into the existing port with no machining or modification to the housing, matching the original installation method precisely.
- Confirmed Fitment for RD27-100 and RD27-120 — Verified for multiple configurations of the RD27-100 and RD27-120 Hydrostatic Vibratory Rollers, covering all listed machine variants in the Wacker Neuson lineup.
- Protects Hydraulic System Integrity — A failed or missing seal plug can allow fluid loss or contamination ingress, leading to hydraulic pressure drop and potential damage to pumps, motors, or drive components in the roller.
- Correct Part for Critical Fluid Passages — Using the OEM-specified plug eliminates the risk of thread mismatch or incorrect depth seating that can compromise port sealing in high-pressure hydraulic environments.
A seal plug closes and seals an unused or service port within a machine's hydraulic or fluid circuit, preventing fluid from escaping and keeping contaminants from entering the system. In a hydrostatic vibratory roller like the RD27 series, maintaining sealed hydraulic passages is essential to sustaining the drive pressure and vibration output that the machine depends on for effective compaction. When a seal plug fails — through cracking, cross-threading, or simple wear — fluid loss can trigger pressure drops that impair travel, steering, or drum vibration, and contamination can cause accelerated wear throughout the hydraulic system.
