Wacker Neuson 5000076044 Union Barbed Straight Fitting

The Wacker Neuson Union Barbed Straight Fitting is a genuine OEM component designed for the RS600 and RS800 series single drum vibratory rollers. As a direct factory replacement, part is manufactured to the same specifications as the original, ensuring a correct, leak-free connection in the machine's fluid circuit. Verified fitment spans multiple RS-series configurations including the RS600, RS600A, RS800, RS800A, RS800H, RS800V, RSS800A, and related variants.

Key Features

• Genuine OEM Material Integrity — Manufactured to the same barb geometry and union tolerances as the original fitting, ensuring a secure, pressure-rated connection without distortion or creep.
• Barbed Union Design for Positive Hose Retention — The barbed profile grips flexible hose lines firmly, preventing pull-out or slippage under vibration and fluid pressure typical of roller operation.
• Broad RS-Series Fitment — Confirmed compatibility across RS600, RS600A, RS800, RS800A, RS800H, RS800V, and RSS800A single drum vibratory roller configurations.
• Maintains Fluid Circuit Performance — A sound fitting keeps coolant, hydraulic, or fuel lines flowing without restriction; a cracked or loose fitting can cause fluid loss, overheating, or system contamination.
• Fuel and Fluid System Safety — Correct fitting integrity is critical in fuel and hydraulic lines; using a matched OEM replacement eliminates the risk of mismatched barb sizing that can lead to leaks or hose failure under load.

A union barbed straight fitting serves as a inline connector between two sections of flexible hose, allowing fluid — whether coolant, fuel, or hydraulic fluid — to pass through a sealed, continuous line. The barbed ends bite into the inner wall of the hose to hold it firmly in place, while the union body allows the two hose ends to be joined in a straight run. When this fitting cracks, corrodes, or loosens, it can cause fluid leaks that compromise machine performance, create fire hazards in fuel systems, or lead to overheating in cooling circuits.
