The Wacker Neuson Fuel Tank Cap is a genuine OEM component designed for RD27-100 and RD27-120 series hydrostatic vibratory rollers. Sourced directly from Wacker Neuson, this cap meets the exact specifications of the original part installed on the machine at the factory. It is confirmed to fit multiple RD27-100 and RD27-120 configurations, including standard and traction control variants. Replacing a worn, cracked, or missing fuel tank cap with the correct OEM part keeps the fuel system sealed and the roller operating as intended.
Key Features
- OEM-Spec Seal Integrity — Engineered to deliver the correct compression fit and venting behavior for the RD27 fuel tank, preventing leaks, contamination, and pressure imbalance.
- Direct-Fit Installation — Threads directly onto the RD27-100 and RD27-120 fuel tank filler neck with no trimming, adapting, or additional hardware.
- Broad RD27 Series Coverage — Compatible across a wide range of RD27-100 and RD27-120 machine configurations, including standard hydrostatic and traction control variants.
- Protects Fuel System Cleanliness — A properly sealed cap blocks dirt, debris, and moisture from entering the tank — contamination that can clog fuel filters, damage injectors, and lead to costly repairs.
- Fuel Safety Compliance — A correctly fitting OEM cap maintains the closed fuel system required for safe operation of diesel-powered compaction equipment — critical on active work sites.
The fuel tank cap seals the filler opening on the machine's diesel fuel tank, keeping the fuel supply protected from dirt, water, and airborne debris during operation and storage. It also allows controlled venting to prevent pressure buildup or vacuum lock that could restrict fuel flow to the engine. A cap that is cracked, stripped, or missing exposes the tank to contamination and presents a fuel spillage risk — both of which can lead to engine damage and unsafe operating conditions on the job.
