Wacker Neuson 5100013387 O-Ring Seal

The Wacker Neuson 5100013387 is a genuine OEM O-Ring Seal designed for the RD-series tandem roller lineup, covering RD18, RD24, RD27, RD28, RD40, and RD45 models across standard, combination drum, open drum, smooth drum, and DPF-equipped configurations. As a direct factory replacement, this seal meets the same material and dimensional standards as the original component installed at the factory. With fitment spanning walk-behind and ride-on articulated tandem rollers in both US and international specifications, part number 5100013387 is a widely used service part across the RD product family. Keeping an accurate part number on hand ensures you get the correct seal the first time and get your roller back in service quickly.

Key Features

• Genuine OEM Material Grade — Manufactured to Wacker Neuson's original compound and durometer specification, ensuring the seal compresses and seats correctly under operating pressures and temperatures found in tandem roller hydraulic and fluid systems.
• Drop-In Replacement Fit — Dimensionally identical to the original, this O-Ring Seal seats into the same groove or port without any trimming, shimming, or machining — critical for maintaining a leak-free interface.
• Broad RD-Series Compatibility — Fits RD18, RD24, RD27, RD28, RD40, and RD45 tandem rollers across walk-behind and ride-on articulated configurations, including smooth drum, open drum, combination, and DPF-equipped variants.
• Leak Prevention at the Source — A properly seated O-Ring Seal maintains fluid pressure integrity throughout the hydraulic or fluid circuit; a worn or cracked seal allows fluid to bypass, causing pressure loss, contamination, and progressive system damage.
• Fluid System Integrity — Using the correct OEM-spec seal on hydraulic or fluid connections on compaction equipment is essential to prevent uncontrolled fluid loss that can compromise drum drive performance and braking response.

An O-Ring Seal is a precision loop of elastomeric material installed at fluid connections, port faces, or component interfaces to prevent the passage of hydraulic fluid, oil, or coolant between mating surfaces. In tandem rollers like the RD series, these seals appear throughout the hydraulic drive system, drum assemblies, and fluid circuits, where they maintain pressure and prevent cross-contamination between circuits. When an O-Ring Seal degrades — through heat cycling, compression set, or chemical exposure — it loses its ability to maintain a static or dynamic seal, leading to visible leaks, pressure drop, and potential damage to surrounding components if not addressed promptly.
