Wacker Neuson 5000021670 Usit Ring

The Wacker Neuson is a genuine OEM Usit Ring designed for the extensive AR series external concrete vibrators, select DPU reversible vibratory plates, and AP battery-powered vibratory plates. This factory-sourced sealing ring covers a broad range of AR 41, AR 42, AR 43, AR 44, AR 51, AR 52, AR 53, AR 54, and AR 75 series external vibrators across multiple voltage and frequency configurations, along with DPU 7060, DPU 7060SC, DPU 7060Fe, DPU 7060Fet, DPU 9070, DPU 100-70, and AP1840e, AP1840we, AP1850e, and AP1850we battery plate models. As a genuine Wacker Neuson part, the is manufactured to the same specification as the original component, ensuring a direct, like-for-like replacement with no guesswork on fit or material grade. Keep this small but critical seal on hand to maintain the integrity of your vibrator or compaction equipment and avoid unnecessary fluid migration or premature wear at the sealing point.

Key Features

• OEM Sealing Integrity — Manufactured to Wacker Neuson's original material and compression specification, ensuring the Usit Ring delivers the same sealing performance as the part it replaces.
• Drop-In Replacement — Matches the original seating geometry of the 5000021670 position, installing directly without modification to housings, bores, or fasteners.
• Exceptionally Wide Fitment — A single part number covers AR 41 through AR 75 external vibrator series, DPU 7060 and DPU 100-70 reversible vibratory plate families, and AP1840 and AP1850 battery-powered vibratory plate models.
• Leak Prevention at the Source — A correctly seated Usit Ring prevents fluid bypass at threaded or bolted interfaces; a degraded ring can allow contamination ingress or fluid loss, accelerating wear on internal components.
• Fuel and Fluid System Compliance — In external vibrator and compaction applications, maintaining a properly functioning seal is essential to prevent hydraulic or lubricant leakage that could affect safe operation and environmental compliance on the jobsite.

A Usit Ring is a combined sealing element — typically a rubber or elastomeric ring bonded or paired with a metal or plastic support washer — used to create a reliable, leak-free seal at threaded ports, bolt faces, or housing interfaces. In external concrete vibrators and vibratory compaction equipment, these rings prevent lubricant or hydraulic fluid from migrating past fastener points under the cyclic loading and vibration that these machines generate continuously during operation. When a Usit Ring degrades, flattens, or cracks, the seal at that interface is lost, which can lead to fluid leakage, contamination of surrounding components, and eventual internal damage to the vibrator motor or compaction drive assembly. Replacing a worn 5000021670 Usit Ring promptly is one of the simplest preventive steps to protect the larger assembly.
