Key Features

• Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's original specification, this tank cap delivers the correct thread engagement and seal compression needed to prevent contamination and fluid loss.
• Direct Drop-In Replacement — Engineered to match the original tank opening dimensions exactly, so installation is straightforward with no trimming, adapting, or rework required.
• Broad Model Coverage — Fits RC50, RC70, RC110, RD24-100, RD27-120, RD28-120, RD40-130, and RD45-140 series machines, including DPF, cab, and ROPS variants.
• Protects Tank Contents — A correctly seated tank cap keeps moisture, debris, and contaminants out of the fluid system, preserving fluid quality and protecting downstream components.
• Fuel System Safety — A properly functioning tank cap maintains correct tank pressure balance and prevents fuel or fluid spillage — a critical consideration on operating compaction equipment.

The tank cap seals the fluid reservoir on compaction equipment, preventing contaminants such as dirt, water, and debris from entering the tank during operation and storage. It also plays a role in maintaining correct tank venting or pressure balance, depending on the system design. A worn, cracked, or missing tank cap can allow contamination that degrades fluid quality, accelerates component wear, and potentially leads to costly system damage — making timely replacement with a correct-specification part an important part of routine maintenance.
