The Wacker Neuson 5100011516 is a genuine OEM O-Ring Seal designed for the RD-series tandem roller lineup, covering a wide range of RD24, RD27, RD28, RD40, and RD45 models. Sourced directly from Wacker Neuson, this seal meets the exact material and dimensional tolerances required for proper sealing within these machines. It is a direct-fit replacement for all standard, combination (C), offset drum (O), DPF, and.3-series variants across the RD24-100, RD27-120, RD28-120, RD40-130, and RD45-140 tandem roller families.
Key Features
- OEM Material Specification — Manufactured to Wacker Neuson's exact compound and dimensional tolerances, ensuring consistent compression and sealing performance in hydraulic and fluid circuits specific to RD-series tandem rollers.
- Drop-In Sealing Fit — Sized and profiled to seat correctly in the original groove geometry of the RD24, RD27, RD28, RD40, and RD45 platforms — no trimming, stretching, or adaptation needed.
- Broad RD-Series Coverage — Fits standard, open-drum (O), combination (C), DPF, and .3-generation variants across the RD24-100, RD27-120, RD28-120, RD40-130, and RD45-140 tandem roller families, including US-market builds.
- Leak Prevention at the Source — A properly seated O-Ring Seal maintains system pressure and prevents fluid ingress or loss. A failed or worn seal can cause hydraulic leaks, contamination, and loss of drum drive performance on the roller.
- Genuine OEM Part — Supplied as a genuine Wacker Neuson replacement, so the part number 5100011516 maps directly to your machine's parts diagram with no cross-reference guesswork.
An O-Ring Seal is a precision-molded loop of elastomeric material used to create a fluid-tight or pressure-tight seal between two mating components. In tandem rollers like the RD-series, O-rings are used throughout hydraulic circuits, drum drive assemblies, and fluid connections to prevent leaks and keep contaminants out. When an O-ring becomes cracked, compressed flat, or chemically degraded, it loses its ability to seal — leading to hydraulic fluid loss, reduced drive pressure, and potential damage to surrounding components if not addressed promptly.
