Wacker Neuson 5000111278 Hydraulic Fitting SAE #4 Run Tee

The Wacker Neuson is a genuine OEM Hydraulic Fitting SAE #4 Run Tee designed for the RD11AEC and RD11A hydrostatic double drum vibratory rollers. As a direct Wacker Neuson OEM part, the is manufactured to the same specifications as the original fitting, ensuring a proper hydraulic connection within the roller's hydrostatic drive circuit. This fitting is engineered to handle the operating pressures of the RD11 series hydraulic system without compromise.

Key Features

• Genuine OEM Hydraulic Integrity — Manufactured to OEM specification with the correct SAE #4 thread form and run-tee geometry, maintaining leak-free hydraulic circuit performance in demanding roller applications.
• Direct Hydraulic Line Connection — The run-tee configuration allows a straight-through flow path with a branch port, dropping into the existing hydraulic plumbing of the RD11AEC and RD11A without rework or adapters.
• Designed for RD11 Series Tandem Rollers — Confirmed fitment for the RD11AEC and RD11A hydrostatic double drum vibratory rollers, so you can order with confidence.
• Protects Hydrostatic Drive Performance — A correctly seated hydraulic fitting maintains consistent fluid pressure and flow to the drive system; a leaking or damaged fitting can cause erratic drum drive behavior and power loss.
• Corrosion-Resistant Construction — Built to withstand the hydraulic fluid exposure and vibration inherent in a tandem roller environment, supporting long service life in the system.

A hydraulic run tee fitting connects multiple hydraulic lines at a single junction, allowing fluid to flow straight through while also branching off to a secondary circuit. In the RD11 series tandem roller, hydraulic fittings like this one are critical to maintaining the correct pressure and flow within the hydrostatic drive system that powers and vibrates the drums. When a fitting develops a leak or cracks under pressure, hydraulic fluid loss can lead to reduced drive force, inconsistent compaction output, and potential damage to pumps or motors downstream.
