The Wacker Neuson is a genuine OEM SAE #8 ORB Breather designed for RD12, RD16, and CB14B series tandem rollers and soil and asphalt compactors. As a direct OEM replacement, part is manufactured to the same specifications as the original component installed at the factory, ensuring a correct, trouble-free installation every time. Confirmed fitment spans the RD12-90, RD12A-90, RD16-90, RD16-100, CB14B-900, and CB14B-1000 model lines, covering a wide range of walk-behind and ride-on tandem roller configurations. When your breather shows signs of blockage or wear, replacing it with the correct Wacker Neuson part keeps your hydraulic or fluid system venting properly and your machine running as intended.
Key Features
- Genuine OEM Venting Spec — Manufactured to the exact port sizing and flow rating of the original SAE #8 ORB fitting, so the breather performs precisely as Wacker Neuson engineered it to.
- SAE #8 ORB Thread Interface — Threaded to the SAE straight-thread O-ring boss (ORB) standard, allowing direct installation into the original port with no adapters or thread modifications.
- Broad Tandem Roller Coverage — Fits RD12-90, RD12A-90, RD16-90, and RD16-100 tandem roller variants, as well as CB14B-900 and CB14B-1000 soil and asphalt compactors.
- Protects Hydraulic System Integrity — A functioning breather maintains correct pressure balance in the reservoir or housing; a clogged or failed unit can cause seal damage, fluid contamination, or overheating under load.
- Fluid Contamination Control — OEM filtration media and housing materials prevent airborne debris from entering the system during thermal cycling, extending the service life of hydraulic components.
A breather is a vented filter fitted to a fluid reservoir or gearbox housing that allows air to move in and out as fluid levels and temperatures change during operation. Without a properly functioning breather, pressure differentials build inside the housing, which can force fluid past seals, draw in unfiltered air, or collapse reservoir walls. On tandem rollers and compactors like the RD and CB14B series, where hydraulic systems work hard under continuous vibration and load, a blocked or damaged breather accelerates fluid degradation and can lead to costly hydraulic component failures. Replacing a worn breather with the correct OEM unit — Wacker Neuson 5000163335 — restores proper system breathing and helps protect the entire hydraulic circuit.
