The Wacker Neuson is a genuine OEM Hydraulic Fitting 8-12 St designed for the RD11AEC hydrostatic double drum vibratory roller and a range of CRT48 and CRT60 ride-on concrete trowels, including Power Steer and standard configurations. Sourced directly from Wacker Neuson, this fitting carries the same specifications as the original component installed at the factory, ensuring a correct, leak-free connection within the hydraulic circuit. Compatible machines include the CRT48-35L-PS, CRT48-35V-PS, CRT48-37V-PS, CRT48-57K-PS, CRT60-66K, and the RD11AEC roller. If your hydraulic system is showing signs of seeping connections or pressure loss at a fitting point, part number is the correct OEM replacement to restore system integrity.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's hydraulic line specifications, ensuring the correct thread form, port size, and sealing surface for a pressure-tight connection.
- Direct-Swap Installation — Matches the original fitting geometry on the RD11AEC and CRT series hydraulic plumbing, threading in without reworking lines or adapters.
- Broad CRT and RD Series Compatibility — Fits the CRT48-35L-PS, CRT48-35V-PS, CRT48-37V-PS, CRT48-57K-PS, CRT60-66K, and the RD11AEC double drum roller across both standard and EU-spec machines.
- Maintains Hydraulic Pressure — A sound fitting keeps the hydrostatic drive and hydraulic steering circuits operating at rated pressure; a failed or corroded fitting risks fluid loss and loss of drive or steering response.
- Hydraulic System Safety — Correct fitting torque and thread engagement prevent pressurized fluid leaks that can create slip hazards on the deck and present burn risks to operators.
A hydraulic fitting connects sections of hydraulic hose or tubing within a machine's fluid power circuit, maintaining a sealed pathway for pressurized hydraulic oil. On ride-on trowels like the CRT48 and CRT60 series, the hydraulic system powers the blade pitch adjustment and, on Power Steer models, the steering mechanism — meaning a leaking or failed fitting can directly compromise controllability and finishing performance. On the RD11AEC tandem roller, the hydrostatic drive circuit relies on leak-free connections throughout to deliver consistent drum speed and travel force; even a minor fitting failure can result in pressure drop, erratic drive response, or a complete loss of propulsion.
