Wacker Neuson 5000094944 O-Ring

The Wacker Neuson O-Ring is a genuine OEM sealing component designed for the RD7 and RD10 series walk-behind tandem rollers and the DPU 4045H, DPU 4545H, DPU 5045H, DPU 5545H, DPU 6055, and DPU 6555 series reversible vibratory plate compactors. As a factory-sourced part, the is manufactured to the exact material grade and dimensional tolerances specified by Wacker Neuson, ensuring a proper seal across all applicable hydraulic and fluid circuits. This O-Ring is a direct-fit replacement that installs without modification, keeping fluid containment and system pressure where it needs to be. Confirm your machine's model number against the fitment list before ordering to ensure this is the correct O-Ring for your application.

Key Features

• Exact Material and Dimensional Tolerancing — Manufactured to Wacker Neuson's specified compound and cross-section dimensions, ensuring full sealing contact and compression without over- or under-seating.
• Genuine OEM Part — Sourced directly from Wacker Neuson; part number 5000094944 matches the original part replaced at the factory, with no substitutions in material or geometry.
• Broad Cross-Family Fitment — Compatible with the RD7 and RD10 tandem roller series and a wide range of DPU reversible vibratory plate compactors, from the DPU 4045H through the DPU 6555 series.
• Maintains Hydraulic and Fluid Integrity — A correctly seated O-Ring prevents fluid weeping, pressure loss, and contamination ingress — all of which can accelerate wear in pumps, valves, and hydraulic actuators.
• Fluid and Pressure Compatibility — Formulated to withstand the hydraulic fluid types and operating pressures found in Wacker Neuson compaction equipment, resisting swelling, cracking, and hardening over time.

An O-Ring is a precision-molded elastomeric seal that sits in a machined groove between two mating surfaces or around a shaft or port, creating a pressure-tight barrier that prevents fluid or air from escaping. In hydraulic compaction equipment like the DPU series reversible plates and RD tandem rollers, O-Rings are critical at pump connections, valve bodies, and fluid passages where maintaining system pressure directly determines compaction force and drive performance. When an O-Ring wears, hardens, or is damaged during a service interval, the resulting leak can cause erratic machine behavior, loss of compaction output, or hydraulic fluid contamination — making timely replacement with the correct part essential.
