The Wacker Neuson Seal Nut is a genuine OEM component designed for the RC50, RC70, RC110, and their P and VO variant single drum soil compactors. Sourced directly from Wacker Neuson, this part meets the same specifications as the original hardware installed at the factory. It is a confirmed fit across a wide range of RC series machines, including CAB, ROPS, DPF, and US-market configurations. If you are servicing an RC50, RC70, RC70vo, RC110, or any of their padfoot variants, part number is the correct replacement.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's original material and dimensional spec, ensuring the nut maintains proper sealing compression without distortion or leakage under working loads.
- Drop-In Replacement — Threads and sealing surfaces match the original exactly, so installation follows the same procedure as the factory-fitted part with no rework required.
- Broad RC Series Coverage — Fits RC50, RC50p, RC70, RC70p, RC70vo, RC110, and RC110p machines across standard, US-market, DPF, CAB, and ROPS configurations.
- Preserves Joint Integrity — A correctly seated seal nut prevents fluid ingress and fastener loosening at the joint, keeping the compactor running at full operational capacity across demanding compaction cycles.
- Genuine Wacker Neuson Part — Part number 5100022999 is an authorized OEM replacement, giving you full traceability and confidence that the part leaving your shelf matches what Wacker Neuson specifies for the application.
A seal nut combines the function of a standard fastener with an integrated sealing element, preventing fluid, debris, or moisture from passing through the threaded connection point. On heavy compaction equipment like the RC series soil compactors, these fasteners are exposed to constant vibration and environmental stress, making the condition of the sealing element critical to joint reliability. When a seal nut wears or fails, it can allow contamination into sensitive areas or permit fluid loss, which leads to accelerated wear of surrounding components and unplanned service intervals.
