Wacker Neuson 5000111263 Hydraulic Fitting SAE #12 Tube Inlet

The Wacker Neuson is a genuine OEM Hydraulic Fitting SAE #12 Tube Inlet designed for the RD11 series hydrostatic double drum vibratory rollers, including the RD11A, RD11V, and RD11AEC models. As a direct-from-manufacturer component, it is produced to the exact dimensions and thread specifications required for a leak-free hydraulic connection in these machines. Sourcing the correct OEM fitting is critical on high-pressure hydraulic circuits — an imprecise fit can compromise system integrity and affect drum drive performance. Confirm part number against your machine's parts diagram before ordering to ensure correct application.

Key Features

• OEM-Spec Thread and Port Geometry — Manufactured to the exact SAE #12 tube inlet dimensions required for correct sealing and rated pressure retention in the RD11 hydraulic circuit.
• Direct-Connect Installation — Mates directly to the hydraulic line and port on the RD11A, RD11V, and RD11AEC without modification to fittings, lines, or adjacent hardware.
• RD11 Series Fitment — Verified for the RD11A, RD11V, and RD11AEC hydrostatic double drum vibratory rollers across their respective machine configurations.
• Hydraulic System Integrity — A correctly seated tube inlet fitting maintains consistent fluid flow and pressure to the hydrostatic drive system, supporting drum vibration and propulsion performance across the full operating range.
• Leak Prevention at the Inlet Point — Using the OEM-spec fitting eliminates the risk of thread mismatch or under-rated port connections that can result in hydraulic fluid weeping or line failure under load.

A hydraulic tube inlet fitting serves as the threaded connection point where a pressurized hydraulic line enters a component in the machine's hydrostatic drive circuit. On tandem rollers like the RD11 series, the hydraulic system powers both drum vibration and the propulsion drive — so maintaining a secure, correctly rated connection at every inlet point is essential to normal operation. When a fitting corrodes, cross-threads, or fails to seal, the result is hydraulic fluid loss, pressure drop, and potential loss of drive or vibration function.
