The Wacker Neuson Seal Nut is a genuine OEM component designed for the RD and RC series compactors, including RD24-100, RD28-120, RD40-130, and RD45-140 tandem rollers, as well as RC50, RC70, and RC110 single drum soil compactors. Sourced directly from Wacker Neuson, this seal nut meets the exact specifications of the original part installed at the factory. It covers an extensive range of model variants including C, O, DPF, CAB, and ROPS configurations across both standard and US-market machines. When it comes to maintaining your compactor's hydraulic and drivetrain integrity, using the correct OEM seal nut ensures a proper seal and consistent clamping force every time.
Key Features
- OEM-Grade Sealing Performance — Manufactured to Wacker Neuson's original material and thread specification, ensuring the correct compression and sealing force for this application.
- Direct Drop-In Replacement — Matches the original thread profile and dimensions for straightforward installation without rework or adaption.
- Broad Compactor Compatibility — Fits RD24-100 through RD45-140 tandem rollers and RC50 through RC110 single drum soil compactors, covering CAB, ROPS, DPF, C, and O variants.
- Prevents Fluid Loss and Fastener Loosening — A worn or missing seal nut can allow fluid ingress or egress and lead to fastener back-out under vibration — this OEM part restores the designed sealing function.
- Genuine Wacker Neuson Part — Part number 5100011511 is an authentic OEM component, giving you traceability and confidence that the part matches your machine's original build specification.
A seal nut combines the function of a standard fastener with an integrated sealing element, preventing fluid leakage and contaminant ingress at threaded connections exposed to pressure or harsh operating environments. On vibratory compactors and soil compaction equipment, these connections are subject to constant vibration and load cycling, making a correctly rated seal nut critical to maintaining system integrity. When a seal nut fails or is worn, it can allow hydraulic fluid to escape or external debris to enter, leading to accelerated wear or system pressure loss that directly affects compaction performance.
