Wacker Neuson 5100011500 O-Ring Seal

The Wacker Neuson 5100011500 is a genuine OEM O-Ring Seal designed for the RD series tandem rollers and RC series single-drum soil compactors. This seal covers an exceptionally wide range of machines across both product families, including RD18, RD24, RD27, RD28, RD40, and RD45 tandem rollers as well as RC50, RC70, and RC110 single-drum soil compactors in smooth-drum, padfoot, and vibratory offset configurations. As a genuine Wacker Neuson part, the 5100011500 is manufactured to the same specification as the original component, ensuring a correct, leak-free fit every time. Whether you are servicing a walk-behind tandem roller or a large-frame single-drum compactor, this O-Ring Seal is the direct replacement your machine calls for.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's original material and dimensional specification, delivering the compression rating and fluid compatibility required for hydraulic and fluid systems in compaction equipment.
• Direct Drop-In Replacement — Matches the original seal profile and cross-section, seating correctly in the existing groove without reworking or resizing the mating surfaces.
• Broad Cross-Family Fitment — Confirmed for RD18, RD24, RD27, RD28, RD40, and RD45 tandem rollers and RC50, RC70, and RC110 single-drum soil compactors across standard, padfoot, DPF, CAB, and ROPS variants.
• Prevents Fluid Loss and Contamination — A properly seated O-Ring Seal maintains system pressure and blocks ingress of dirt and moisture, both of which can accelerate wear in hydraulic and drive components.
• Fluid-System Safety Compliance — Replacing a failed or weeping seal promptly keeps hydraulic pressure within design limits, preventing unsafe machine behavior and protecting downstream components from pressure-related damage.

An O-Ring Seal creates a compressed, leak-proof barrier between two mating surfaces or within a port, fitting, or housing inside the machine's hydraulic, lubrication, or fluid-transfer circuit. When the seal is in good condition, it holds system pressure steady and prevents fluid from escaping or contaminants from entering. As an O-Ring ages or is exposed to heat cycling and chemical exposure, it can harden, crack, or flatten, causing weeping or outright leaks that drop system pressure, introduce air into hydraulic lines, and accelerate wear on pumps, motors, and cylinders. Replacing a degraded seal at the first sign of a leak is one of the most cost-effective preventive maintenance steps on any roller.
