Key Features
- Genuine OEM Material Integrity — Manufactured from the same rubber compound specification as the original, ensuring correct compression, flexibility, and environmental sealing performance over time.
- Drop-In Replacement — Engineered to seat and retain exactly as the original cap, with no trimming or adaptation needed to fit the mounting point.
- Broad RD27 Series Coverage — Fits RD27-100 and RD27-120 rollers across standard hydrostatic and traction control configurations, covering a wide range of machine serial numbers.
- Protects Critical Components — A correctly fitted rubber cap keeps contaminants, moisture, and debris out of the port or fitting it covers, preventing premature wear or corrosion of the underlying components.
- Correct Part, Verified — Part number 5000171994 is confirmed against Wacker Neuson fitment data for the RD27 roller family, so you can order with confidence.
A rubber cap serves as a protective cover for an exposed port, fitting, or connection point on the machine. Its role is to seal out dirt, water, and debris that could compromise the component underneath — whether that is a hydraulic port, fluid reservoir opening, or electrical connection. When a rubber cap cracks, hardens, or goes missing, that port is left open to contamination, which can lead to corrosion or internal damage over time. Replacing a worn cap promptly is a simple, low-cost step that protects far more expensive components on the RD27 roller.
