The Wacker Neuson O-Ring Seal is a genuine OEM component designed for the RD24-100, RD27-120, RD28-120, and RC110 series tandem rollers. Sourced directly from Wacker Neuson, this part meets the exact material and dimensional standards of the original seal installed at the factory. Fitment spans a wide range of RD-series configurations including standard, cab, open ROPS, DPF, and US-spec variants, as well as RC110 ROPS and CAB models — making the correct choice across a broad spread of the tandem roller lineup.
Key Features
- OEM-Grade Elastomer Material — Manufactured to Wacker Neuson's specified compound and durometer rating, ensuring correct compression set and long-term sealing integrity under hydraulic or fluid system pressures.
- Drop-In Replacement — Matches the original cross-section and diameter exactly, seating into the existing groove without reworking the bore or mating surfaces.
- Wide RD and RC Series Fitment — Compatible with RD24-100, RD27-120, RD28-120, and RC110 tandem rollers across standard, cab, open, DPF, and US-spec configurations.
- Leak Prevention at the Source — A correctly seated O-Ring Seal maintains fluid containment within the system; a worn or deformed seal allows fluid bypass, leading to pressure loss and potential damage to adjacent components.
- Genuine OEM Part — Carries Wacker Neuson part number 5100024321, ensuring you receive the correct seal for your machine rather than a dimensionally similar substitute.
An O-ring seal creates a pressure-tight barrier between two mating surfaces or within a bore, preventing hydraulic fluid, oil, or coolant from escaping the system. In compaction equipment like tandem rollers, these seals are critical to maintaining consistent hydraulic pressure for drum drive and vibration systems. When an O-ring hardens, cracks, or loses its original profile, it can no longer form an effective seal — resulting in fluid weeping, pressure drop, and accelerated wear on the components it was protecting.
