The Wacker Neuson Ball Closure Cock is a genuine OEM component designed for the RD40-130 and RD45-140 series tandem rollers. Sourced directly from Wacker Neuson, this part carries the same specification as the unit installed at the factory, ensuring an accurate match for your machine. Compatible across a broad range of RD40-130 and RD45-140 variants — including standard, C, O, DPF, and US-market configurations — the covers one of the most widely deployed tandem roller families in the Wacker Neuson lineup. Verify your model number before ordering to confirm the correct fit for your specific machine.
Key Features
- Genuine OEM Sealing Integrity — Built to Wacker Neuson's exact bore tolerances and seat geometry, ensuring a leak-free shutoff every time the valve is operated.
- Direct-Swap Installation — Matches the original port threading and body dimensions, so the 5100011559 installs directly into the existing fitting without adapters or rework.
- Broad RD-Series Coverage — Fits RD40-130 and RD45-140 tandem rollers across standard, C, O, DPF, and US-spec variants, spanning multiple production series.
- Positive Flow Control — A fully seated ball closure cock provides immediate, positive shutoff of fluid flow, protecting downstream components during service and preventing unintended discharge on site.
- Fluid System Safety — A faulty or leaking shutoff valve compromises your ability to isolate fluid circuits safely during maintenance; a correctly functioning replacement restores safe servicing practice.
A ball closure cock is a quarter-turn shutoff valve used to start or stop the flow of fluid through a circuit. In tandem rollers like the RD40-130 and RD45-140, it provides operators and technicians with a reliable means of isolating a fluid line during routine service or repairs. When the valve begins to leak or fails to seat fully, fluid can escape into areas where it shouldn't, creating both a mess and a potential hazard — making timely replacement essential to keeping the machine serviceable.
