The Wacker Neuson 5100012391 is a genuine OEM Adjustable Elbow designed for the RC50, RC70, RD18, RD40, and RD45 series of single-drum soil compactors and tandem rollers. As a direct OEM part, the 5100012391 is manufactured to the same standards as the original component it replaces, ensuring proper routing, sealing, and connection geometry within the machine's fluid or air system. This Adjustable Elbow fits an extensive range of configurations across both the RC and RD model families, including DPF, CAB, ROPS, and open-canopy variants, as well as US-market and standard-market machines.
Key Features
- Genuine OEM Construction — Manufactured by Wacker Neuson to original tolerances, ensuring the elbow seats, seals, and articulates exactly as intended within the hydraulic or fluid routing system of your compactor or roller.
- Adjustable Angle Design — The swivel or adjustable elbow configuration allows precise line positioning during installation, eliminating stress on connected hoses or tubing and accommodating tight routing in confined machine compartments.
- Broad Cross-Family Compatibility — A single part number covering the RC50, RC50p, RC70, RC70p, RC70vo, RD18-80, RD18-100, RD40-130, RD45-140 series and their sub-variants, including DPF, CAB, ROPS, C, O, and US configurations.
- Maintains Leak-Free System Integrity — A worn, cracked, or mismatched elbow fitting can cause fluid leaks, pressure loss, or line chafing that leads to system failure; a correctly fitted OEM elbow keeps the circuit sealed and operating at rated pressure.
- OEM Part Number Traceability — Part number 5100012391 is the verified Wacker Neuson OEM reference, giving you confidence that the fitting matches the original specification listed in your machine's parts manual.
An adjustable elbow is a threaded or swivel-type fitting that connects sections of hydraulic, coolant, fuel, or air line at a variable angle, allowing the technician to orient the downstream hose or pipe without twisting the line under pressure. In compactors and rollers, these fittings are used wherever rigid tubing must change direction within a confined engine or hydraulic compartment. When an elbow fitting cracks, strips, or corrodes, it can introduce leaks that starve downstream components of fluid or allow contaminants into a closed system, resulting in accelerated wear or component failure.
