Wacker Neuson 5000071121 Sealing Ring

The Wacker Neuson is a genuine OEM Sealing Ring designed for a wide range of Wacker Neuson equipment, including PT2H and PT3H centrifugal trash pumps, RD7 series tandem rollers, DS70 vibratory rammers, and an extensive lineup of DPU reversible vibratory plate compactors. As a direct factory replacement, this sealing ring is produced to the exact material and dimensional standards specified for each machine it serves. Confirmed fitment spans the DPU 2540H through DPU 6555 families, DPS series asphalt plates, RD25 and RD7H roller variants, and multiple PT2H and PT3H pump configurations. Whether you're servicing a pump, a roller, or a heavy-duty diesel plate, part number is the correct OEM-sourced component for the job.

Key Features

• OEM Material Integrity — Manufactured to Wacker Neuson's exact compound and dimensional spec, ensuring the sealing ring maintains proper compression and fluid containment across its full service life.
• Drop-In OEM Replacement — Engineered to seat correctly in the original groove geometry without trimming or modification, making installation straightforward during scheduled service or field repair.
• Broad Cross-Family Fitment — A single part number covers PT2H and PT3H trash pumps, RD7 tandem rollers, DS70 rammers, DPS asphalt plates, and the full DPU reversible vibratory plate range from 2540H through 6555 variants.
• Leak Prevention Where It Counts — A correctly seated sealing ring prevents fluid migration between mating surfaces, keeping hydraulic fluid, coolant, or pump media where it belongs and protecting surrounding components from contamination damage.
• Fluid System Safety — On hydraulic and pump-driven machines, a failed or worn sealing ring can allow fluid loss or ingestion of contaminants — replacing it with the correct OEM part maintains the integrity of pressure and fluid-management systems.

A sealing ring creates a fluid-tight barrier between two mating surfaces — such as a pump housing joint, a hydraulic port face, or a fluid passage cover — preventing internal and external leakage. When a sealing ring degrades, hardens, or is damaged during disassembly, it loses the elasticity needed to maintain compression against the mating surfaces, allowing fluid to bypass the seal. Replacing it promptly with the correct-spec part, such as Wacker Neuson 5000071121, restores the pressure integrity and contamination resistance that these machines depend on across demanding compaction, pumping, and rolling applications.
