Wacker Neuson 5100005971 Grooved Ring

The Wacker Neuson 5100005971 is a genuine OEM Grooved Ring designed for the DPU80r, DPU90r, and DPU110r series reversible vibratory plate compactors. As a direct OEM replacement, this part is manufactured to the same specifications as the original component installed at the factory, ensuring a proper fit within the hydraulic or drive system it serves. Compatible models include the DPU80rLec770, DPU80rLem770, DPU90rLec770 US, DPU90rLem770 US, DPU110rLec870, DPU110rLec970, DPU110rLem870, DPU110rLem970, and their US-market variants. Keeping this seal in sound condition is essential to maintaining the performance and integrity of your DPU-series compactor on soil and aggregate compaction applications.

Key Features

• OEM Seal Material Integrity — Manufactured to the original material grade and dimensional tolerances, ensuring the correct compression and sealing performance for the hydraulic circuit on DPU-series reversible plate compactors.
• Drop-In Replacement — Matches the original groove profile and ring geometry, allowing the part to seat correctly in its housing without rework or adaptation.
• Broad DPU-Series Coverage — Fits a wide range of DPU80r, DPU90r, and DPU110r models including Lec and Lem engine variants across both standard and US-market configurations.
• Leak Prevention — A worn or cracked grooved ring allows fluid to bypass the seal, leading to pressure loss and potential system damage; replacing it promptly restores proper hydraulic containment.
• Genuine Wacker Neuson OEM Part — Supplied as part number 5100005971 directly within the Wacker Neuson parts catalog, confirming authenticity and traceability for your equipment records.

A grooved ring is a dynamic sealing element used within hydraulic or reciprocating assemblies to prevent fluid from escaping past moving components. The ring's profile allows it to flex under pressure, maintaining a tight seal against the bore or shaft surface it contacts. When the ring wears, hardens, or takes damage, the seal is compromised — causing fluid leakage, loss of hydraulic pressure, and degraded machine performance that can ultimately take a compactor out of service if left unaddressed.
