Wacker Neuson 5100013547 Seal Nut

The Wacker Neuson Seal Nut is a genuine OEM component designed for the RD24-100, RD27-120, RD28-120, RD40-130, RD45-140 tandem roller series and RC110 compactors, covering standard, cab, open ROPS, and DPF configurations. As a factory-sourced part, the is manufactured to the same specifications as the original, ensuring correct fit and function across the full range of compatible machines. This Seal Nut is a direct replacement that installs exactly as the original, with no guesswork on fitment across a broad lineup of Wacker Neuson tandem rollers.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's original material and thread specifications, ensuring the seal nut maintains proper clamping force and leak-free performance at the fastening point.
• Direct Drop-In Replacement — Matches the original thread form and seating profile, allowing straightforward installation without reworking the mating components.
• Broad Tandem Roller Compatibility — Fits the RD24-100, RD27-120, RD28-120, RD40-130, and RD45-140 series in standard, cab, open ROPS, DPF, and .3 variants, as well as RC110 and RC110P compactors in US and international configurations.
• Prevents Fluid Loss and Fastener Loosening — A worn or missing seal nut can allow fluid seepage or fastener vibration-loosening under compaction loads; replacing it promptly keeps hydraulic or mechanical connections secure and tight.
• Backed by Wacker Neuson OEM Sourcing — Part number 5100013547 is sourced directly through Wacker Neuson's authorized parts chain, so you receive the correct part with full traceability to the original equipment specification.

A seal nut combines the clamping function of a standard nut with an integrated sealing element — typically a captive washer or deformable collar — that prevents fluid or pressure from escaping around the fastener once torqued down. On tandem rollers and compactors, these fasteners appear at hydraulic line connections, drum drive assemblies, and other high-vibration joints where both mechanical retention and a leak-free seal are required simultaneously. When a seal nut wears out or is overtorqued to the point of seal failure, the result is fluid weepage, potential pressure loss in the hydraulic circuit, and accelerated wear on surrounding components — making timely replacement with the correct OEM part essential to keeping the machine running at full compaction capacity.
