Wacker Neuson 5100012479 Greasing Nipple

The Wacker Neuson 5100012479 is a genuine OEM Greasing Nipple designed for a broad range of Wacker Neuson single-drum soil compactors and tandem rollers. This includes the RC50, RC70, and RC110 single-drum soil compactor families, as well as the RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller series. As a genuine OEM component, part 5100012479 is produced to the same specifications as the original hardware installed at the factory, ensuring a consistent, correct fit across every compatible machine. Whether you are servicing a walk-behind tandem roller or a larger soil compactor, this greasing nipple delivers the straightforward, tool-free serviceability your maintenance schedule demands.

Key Features

• Genuine OEM Grease Path Integrity — Manufactured by Wacker Neuson to original specifications, ensuring the grease delivery point maintains the correct thread engagement, ball-check function, and flow characteristics required for proper lubrication.
• Direct Drop-In Replacement — Matches the original thread size, head profile, and seating geometry so it installs directly into the existing port without rework or adapter fittings.
• Broad Cross-Family Fitment — Compatible with the RC50, RC70, and RC110 single-drum soil compactor lines and the full RD18 through RD45 tandem roller series, covering both smooth-drum and padfoot configurations.
• Protects Critical Bearing and Pivot Points — A properly functioning greasing nipple allows grease to enter and purge old lubricant from bearings, drums, and articulation joints; a damaged or clogged nipple leads to dry running and accelerated wear on expensive components.
• Corrosion-Resistant Construction — Built to withstand the mud, water, and grit exposure typical of compaction and rolling applications, maintaining a reliable seal between service intervals.

A greasing nipple — also called a grease fitting or zerk fitting — is the access point through which fresh grease is injected into a bearing housing, pivot pin, drum journal, or articulation joint. It contains a small spring-loaded ball check that opens under grease-gun pressure to admit lubricant and then seals closed to prevent contamination from entering the grease passage. On heavy compaction equipment like the RC and RD series, these fittings are subject to constant vibration, impact, and exposure to abrasive material, which can strip threads, shear the fitting head, or seize the ball check over time. A failed or missing greasing nipple makes routine lubrication impossible, rapidly accelerating wear on the components it serves and leading to costly bearing or joint failures if not addressed promptly.
