Wacker Neuson 5100011517 O-Ring Seal

The Wacker Neuson 5100011517 is a genuine OEM O-Ring Seal designed for the RD40-130 and RD45-140 tandem roller series and the RC110 single-drum soil compactor series. As a direct factory part, 5100011517 is manufactured to the exact material grade, diameter, and compression specification required by Wacker Neuson engineering — ensuring a proper seal against fluid or pressure loss in the application it serves. This O-Ring Seal fits an extensive range of configurations across both roller families, including open-ROPS, cab, DPF, and combination variants, covering US-spec and standard builds alike. Verify your machine's model number against the fitment list before ordering to confirm compatibility.

Key Features

• Exact Material and Dimensional Spec — Manufactured to the precise durometer, cross-section diameter, and inner diameter required for this sealing application; an incorrect O-ring causes immediate leakage or premature failure.
• Genuine OEM Part — Sourced directly from Wacker Neuson; part number 5100011517 matches the factory bill of materials for all listed configurations.
• Broad Fitment Across Two Machine Families — Confirmed fitment for RD40-130 and RD45-140 tandem rollers (open, cab, DPF, and combination variants) and RC110 ROPS and CAB single-drum soil compactors.
• Compression Integrity Under Operating Conditions — A correctly seated O-ring maintains fluid or pneumatic pressure within the sealed circuit; a worn or damaged O-ring results in seepage, loss of pressure, and potential damage to surrounding components.
• Drop-In Service Replacement — Sized to seat directly into the existing groove without modification, making it suitable for field or workshop replacement during scheduled maintenance or seal inspections.

An O-ring seal is a precision loop of elastomeric material that sits in a machined groove between two mating surfaces or components, creating a leak-proof barrier against fluids or pressurized media. In compaction equipment like tandem rollers and single-drum soil compactors, O-rings appear throughout hydraulic circuits, drive assemblies, and fluid reservoirs, where they prevent contamination ingress and maintain system pressure. When an O-ring degrades — through heat cycling, compression set, or chemical exposure — it loses its ability to seat properly, leading to seepage, pressure drop, and accelerated wear on the components it was protecting.
