The Wacker Neuson O-Ring 57 X 2.5-70 Sh is a genuine OEM sealing component designed for DPU series reversible vibratory plate compactors and the DFS 90 powered floor saw. Sourced directly from Wacker Neuson, this O-ring matches the original equipment specification for material grade, durometer hardness, and dimensional tolerancing. Compatible models include the DPU 2430F, DPU 2440F, and DPU 2450F reversible plates, as well as DPS 2040 and DPS 2050 single-direction vibratory plates. Using the correct OEM part ensures a proper seal at its designated joint, protecting internal components from fluid loss, contamination, and pressure drop.
Key Features
- 70 Shore Hardness Compound — The 70 Sh durometer rating provides the correct compression resistance for dynamic sealing applications in vibratory and cutting equipment.
- Exact 57 x 2.5 mm Profile — Dimensioned to seat flush in the original groove without stretching or pinching, delivering a leak-free seal on installation.
- Genuine OEM Part — Manufactured to Wacker Neuson's original design tolerances, ensuring consistent sealing performance across the full operating pressure range of these machines.
- Broad Compaction and Cutting Equipment Fitment — Fits DPU 2430F, DPU 2440F, DPU 2450F, DPS 2040, DPS 2050 vibratory plates, and the DFS 90 powered floor saw.
- Protects Against Fluid Loss and Contamination — A failed or aged O-ring at this location can allow fluid leakage or ingress of debris, leading to accelerated wear of surrounding components.
An O-ring is a precision loop seal that sits in a machined groove between two mating surfaces, creating a pressure-tight barrier against fluid or gas leakage. In vibratory plate compactors and floor saws, O-rings are used throughout hydraulic circuits, fuel systems, and lubrication passages where maintaining sealed pressure is critical to safe and efficient operation. When an O-ring degrades — through heat cycling, chemical exposure, or compression set — it loses its ability to seal, which can result in fluid leaks, loss of hydraulic pressure, or contamination of sensitive internal components.
