Wacker Neuson 5000156204 #8 To 3/8 NPT Straight Fitting

The Wacker Neuson is a genuine OEM #8 To 3/8 NPT Straight Fitting designed for the RT56, RT82, RTx, RTLx, and RTKx series remote-controlled vibratory trench rollers. As a direct OEM replacement, this fitting is manufactured to the same specifications as the original installed component, ensuring a consistent, leak-free hydraulic connection. Compatible across an extensive range of SC2 and SC3 generation trench roller configurations, part number is the correct choice for keeping your machine's hydraulic circuit intact. Verify your model number before ordering to confirm fitment against your specific machine.

Key Features

• Genuine OEM Hydraulic Integrity — Manufactured to the exact thread form and sealing geometry of the original fitting, maintaining rated hydraulic pressure without leakage at the connection point.
• Standard Straight Configuration — The #8 to 3/8 NPT straight profile connects inline hydraulic lines directly, with no bends or offsets, simplifying installation in tight trench roller hydraulic circuits.
• Broad Trench Roller Fitment — Compatible with RT56-SC, RT56-SC2, RT82-SC, RT82-SC2, RTx-SC2, RTLx-SC3, and RTKx-SC3 series machines, covering a wide span of Wacker Neuson remote trench roller generations.
• Hydraulic Circuit Dependability — A correctly seated fitting sustains consistent oil flow and pressure to the roller's drive and vibration systems; a failed or leaking fitting can starve hydraulic components and cause operational faults.
• Fuel and Fluid System Safety — Hydraulic fittings that are improperly sized or worn can introduce air into the system or cause uncontrolled fluid loss; using the correct OEM fitting eliminates these risks at the connection point.

A hydraulic straight fitting serves as the threaded interface between hydraulic hose ends or line fittings and ported components within the machine's hydraulic circuit. The #8 designation refers to the hose-end dash size, while the 3/8 NPT thread mates with standard port threads on valves, blocks, or manifolds. When a fitting cracks, strips, or corrodes, hydraulic fluid can escape under pressure, causing pressure loss in the drive or vibration circuit and potentially damaging downstream components. Replacing a damaged fitting promptly with the correct OEM part restores a sealed, pressure-rated connection and prevents further hydraulic system degradation.
