Key Features

• Genuine OEM Sealing Integrity — Manufactured to the same sealing tolerances as the original cap, preventing fluid contamination and spillage at the filler point.
• Direct Drop-In Replacement — Matches the original thread pattern and cap dimensions for a straightforward swap with no additional hardware.
• Broad Fitment Across Compaction Families — Compatible with the RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller series, plus the RC50, RC70, and RC110 single-drum soil compactors.
• Protects Fluid System Cleanliness — A properly sealing filler cap keeps dirt, debris, and moisture out of the fluid reservoir, protecting internal components from premature wear.
• Fluid Containment Safety — A failed or missing filler cap can result in fluid leaks or contamination that may lead to machine damage or hazardous spills on the worksite; replacing it promptly maintains safe operation.

The filler cap seals the fluid reservoir access point on the machine, preventing contaminants such as dirt, dust, and water from entering the system while keeping fluid from escaping during operation. On compaction equipment like tandem rollers and single-drum soil compactors, maintaining a clean, sealed fluid system is essential to the longevity of hydraulic and drive components. When a filler cap becomes cracked, loses its seal, or goes missing entirely, the risk of fluid contamination or loss increases significantly, which can lead to overheating, accelerated component wear, or unplanned downtime.
