Wacker Neuson 5000079875 Straight Thread Connector Fitting

The Wacker Neuson Straight Thread Connector Fitting is a genuine OEM hydraulic fitting designed for RD7, RD12, RT56, RT82, RTL82, RTK82, RTLx, RTKx, and RTx series tandem rollers and trench rollers. As a direct OEM replacement, this fitting is manufactured to the same tolerances and thread specification as the original, ensuring a leak-free connection in the hydraulic circuit. Fitment spans a wide range of walk-behind tandem rollers and remote-controlled vibratory trench rollers across multiple generations of the Wacker Neuson roller lineup. Verify your machine's model number and serial number before ordering to confirm compatibility with your specific configuration.

Key Features

• Genuine OEM Thread Integrity — Manufactured to the exact thread form and sealing specification of the original, maintaining hydraulic circuit integrity under operating pressure.
• Direct Hydraulic System Replacement — Installs directly into the existing hydraulic port without reworking fittings or adapters, restoring the original fluid routing path.
• Broad Roller Family Coverage — Compatible with RD7, RD12, RT56, RT82, RTL82, RTK82, RTLx, RTKx, and RTx series machines, covering both tandem walk-behind rollers and remote-controlled trench rollers.
• Leak-Free Hydraulic Performance — A damaged or worn straight thread connector fitting can cause hydraulic fluid loss, pressure drop, and loss of drive or vibration function; this OEM fitting restores proper system pressure.
• Hydraulic Safety Compliance — Correct thread engagement prevents uncontrolled hydraulic pressure loss, protecting operators and bystanders from pressurized fluid hazards on active worksites.

A straight thread connector fitting is a hydraulic plumbing component that joins hydraulic lines or hoses to a ported housing using straight (parallel) threads, with sealing achieved through an O-ring or washer at the thread seat rather than a tapered thread form. In a vibratory roller or trench roller, these fittings appear throughout the hydraulic drive and vibration circuits, routing pressurized fluid between the pump, motors, and control valves. When a fitting cracks, strips, or develops a leak at the seat, hydraulic pressure drops and the machine can lose traction, vibration output, or both — making prompt replacement critical to keeping the roller performing at full compaction capacity.
