Wacker Neuson 5000080734 O-Ring .924 X.116 Duro90 3-912

The Wacker Neuson is a genuine OEM O-Ring.924 X.116 Duro90 3-912 designed for a broad range of Wacker Neuson compaction, paving, and material-handling equipment. As a direct OEM part, the meets the original design specification for the hydraulic and fluid systems in which it is used. Fitment covers the RT560 and RT820 vibratory trench roller series, the RD11 and RD880V double drum vibratory roller series, the CRT60 ride-on concrete trowel family — including CRT60-66K, CRT60-74L, and CRT60-74LX variants — and the full WB16 power buggy line. Confirm your model and machine number before ordering to ensure a correct application.

Key Features

• 90 Durometer Compound Integrity — The Duro90 hardness rating delivers the compression resistance needed to maintain a positive seal under hydraulic pressure, resisting extrusion in high-load fluid circuits.
• Genuine OEM Sourcing — Supplied directly through the Wacker Neuson OEM parts program, this o-ring matches the exact material specification and dimensional tolerance of the original installed component.
• Drop-In Dimensional Fit — The .924 inside diameter and .116 cross-section match the original groove geometry, allowing direct installation without machining or shimming.
• Wide Cross-Family Fitment — A single part number covering the RT560, RT820, RT820HT, RD11, RD880V, CRT60 series, and WB16 power buggy variants makes this a practical stocking item for fleets running multiple Wacker Neuson machines.
• Leak Prevention at the Source — A correctly seated o-ring maintains hydraulic and fluid circuit integrity; a worn or cracked seal leads to fluid weeping, pressure drop, and accelerated component wear throughout the system.
• Fluid System Safety Compliance — Maintaining an intact seal in hydraulic and fuel-adjacent circuits prevents uncontrolled fluid release, an important consideration on ride-on and remote-controlled equipment operating near personnel.

An o-ring is a circular elastomeric seal seated in a machined groove between two mating surfaces or fittings. Its job is to prevent fluid — hydraulic oil, coolant, or fuel — from bypassing the joint under pressure or suction. When an o-ring ages, hardens, or sustains mechanical damage, it loses its ability to conform to the mating surfaces and begins to leak. On hydraulic-drive equipment such as trench rollers and tandem rollers, even a minor seal failure can cause pressure loss that affects drive performance and compaction output. Replacing a worn o-ring at first sign of seepage is a low-cost repair that protects the higher-value components around it.
