The Wacker Neuson Cap Plug is a genuine OEM component designed for the RD27-100 and RD27-120 series hydrostatic vibratory rollers, including standard and Traction Control configurations. As a direct OEM replacement, is sourced to the same specifications as the original part, ensuring a correct, no-guesswork installation. This Cap Plug fits across the full range of RD27 tandem roller variants, making it a reliable choice whether you are servicing a standard unit or a Traction Control-equipped machine.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original specification, ensuring the same material grade and dimensional tolerances as the factory-installed part.
- Direct OEM Replacement — Installs into the same port or opening as the original Cap Plug with no rework or adaptation to the surrounding assembly.
- Broad RD27 Series Coverage — Confirmed fitment across multiple RD27-100 and RD27-120 build variants, including both standard Hydrostatic Vibratory Roller and Traction Control configurations.
- Sealing Integrity — A properly seated Cap Plug prevents contamination, fluid intrusion, or pressure loss at the capped port, protecting downstream components from premature wear or damage.
- Fluid System Protection — On hydraulic and fuel system applications, a missing or damaged cap plug can introduce contaminants that compromise system performance; replacing it promptly maintains system cleanliness.
A cap plug seals an unused or temporarily open port, fitting, or passage within the machine's hydraulic, fuel, or fluid system. Its role is to block the entry of dirt, debris, and moisture that could contaminate internal components and cause accelerated wear or system failure. When a cap plug is missing, cracked, or improperly seated, the unprotected port becomes a point of vulnerability — allowing contaminants into lines or cavities where they can cause damage that goes well beyond the cost of the plug itself.
