Wacker Neuson 5000083285 O-Ring .737 x .103 90 Duro Buna N

The Wacker Neuson is a genuine OEM O-Ring.737 x.103 90 Duro Buna N designed for the RT560 and RT820 series vibratory trench rollers. Sourced directly from Wacker Neuson, this part meets the exact material and dimensional specifications required for a proper seal in your machine. It fits multiple RT560 and RT820 configurations, including the RT820HT high-tip variants. Confirming your model number before ordering ensures a correct, trouble-free installation.

Key Features

• 90 Durometer Buna N Construction — The 90-duro Buna N (nitrile rubber) compound delivers the firm compression resistance needed to maintain a leak-free seal under the hydraulic pressures and fluid exposure common in trench roller service.
• Exact OEM Dimensions — At .737 inches inner diameter and .103 inches cross-section, part number 5000083285 seats into its groove without shimming, trimming, or modification, keeping installation straightforward.
• Broad RT-Series Coverage — Confirmed fitment across RT560 and RT820 vibratory trench roller models, including RT820HT configurations, making this a go-to seal for mixed fleets running multiple RT variants.
• Genuine Wacker Neuson OEM Part — As a factory-sourced component, 5000083285 matches the original seal specification for compression set resistance and fluid compatibility, so you are not guessing on material grade.
• Prevents Hydraulic Fluid Loss — A correctly seated O-ring keeps hydraulic pressure stable in the trench roller's drive and vibration systems. A failed or worn seal allows fluid weeping that degrades compaction performance and can lead to component damage if left unaddressed.

An O-ring is a precision sealing element that sits in a machined groove between two mating surfaces or within a hydraulic fitting, preventing fluid from escaping under pressure. In a vibratory trench roller like the RT560 and RT820, O-rings are used throughout the hydraulic circuit — in motors, valves, and manifold connections — where maintaining consistent pressure is critical to driving the drums and the vibration system. When an O-ring degrades, flattens, or develops a nick, it loses its ability to form a complete seal, resulting in hydraulic fluid leaks, pressure drop, and ultimately reduced compaction force or loss of drive function.
