The Wacker Neuson O-Ring Seal is a genuine OEM component designed for the RD18-80, RD18-100, and RC110 series tandem and vibration rollers. Sourced directly from Wacker Neuson, this seal meets the exact material and dimensional standards of the original part it replaces. It is a verified direct replacement across a wide range of RD18 and RC110 variants, including ROPS and CAB configurations. Whether you are servicing an RD18-100c, an RD18-80.3, or an RC110p, part number confirms the correct fit before you order.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's original compound and durometer specifications, ensuring the correct compression set and fluid resistance for roller hydraulic systems.
- Drop-In Installation — Dimensionally identical to the factory seal, seating into the original groove without modification or sizing adjustments.
- Broad RD18 and RC110 Coverage — Fits RD18-80, RD18-80.3, RD18-100, RD18-100c, RD18-100c.3, RC110 ROPS, RC110 CAB, RC110p ROPS, and RC110p CAB variants.
- Leak Prevention at the Source — A properly seated O-ring seal maintains system pressure and prevents fluid migration, keeping hydraulic or drive components operating within designed parameters.
- Genuine Wacker Neuson Part — Supplied as an authentic OEM component, carrying the full Wacker Neuson part number 5100048102 for straightforward verification against your service manual.
An O-ring seal creates a pressure-tight barrier between mating components, preventing hydraulic fluid, oil, or other media from escaping past a joint or fitting. On tandem and vibration rollers like the RD18 and RC110 series, these seals are critical to maintaining the integrity of hydraulic circuits that control drum vibration and propulsion. When an O-ring seal deteriorates — through heat cycling, compression fatigue, or chemical exposure — it can cause fluid leaks that lead to pressure loss, erratic vibration output, and accelerated wear on surrounding components.
