The Wacker Neuson Tank Cap is a genuine OEM component designed for RD7 series tandem rollers and DPU 4045H, DPU 4545H, DPU 5045H, and DPU 5545H series reversible vibratory plate compactors. Sourced directly from Wacker Neuson, this tank cap carries the same part number and specification as the original fitted to your machine at the factory. It is confirmed compatible across a wide range of RD7H and RD7He configurations as well as multiple DPU variants including standard, AP, EC, and EH builds. When the original cap cracks, seals poorly, or goes missing, the is the correct direct replacement to restore proper tank integrity.
Key Features
- OEM Seal Integrity — Manufactured to the original specification, ensuring the cap threads and seats correctly to maintain a secure, leak-free tank closure.
- Drop-In Replacement — Matches the original thread pitch and cap diameter of the tank opening on RD7 and DPU series machines for straightforward swap-out.
- Broad Fitment Coverage — Compatible with RD7H and RD7He tandem rollers and DPU 4045H, DPU 4545H, DPU 5045H, and DPU 5545H reversible vibratory plate compactors across multiple build variants.
- Prevents Contamination — A properly sealing tank cap keeps moisture, debris, and dirt out of the fuel or fluid reservoir, protecting downstream components from contamination damage.
- Fuel System Safety — A failed or missing tank cap can allow vapor escape and create a fire hazard on operating equipment; replacing it promptly restores safe machine operation.
A tank cap seals the filler opening on the machine's fuel or fluid reservoir, keeping the contents contained and the system protected from outside contamination. When it seals correctly, it also maintains any pressure or venting balance the tank is designed to operate at. A cracked, stripped, or absent cap can allow fuel to spill during operation, let water and debris enter the tank, and compromise the performance of the entire fuel delivery system — leading to rough running, injector wear, or pump damage over time.
