Wacker Neuson 5000203708 Ring Cu

The Wacker Neuson Ring Cu is a genuine OEM component designed for the DPU 100-70 reversible vibratory plate compactor. As a factory-sourced part, the is manufactured to the exact material and dimensional tolerances specified for this machine, ensuring a correct, trouble-free installation. This copper sealing ring is a small but critical part of the DPU 100-70's fluid or fastener sealing system, and using the correct OEM replacement helps maintain the integrity of the assembly it serves.

Key Features

• Genuine OEM Copper Construction — Sourced directly from Wacker Neuson, this Ring Cu is produced from copper stock that meets the exact material grade specified for the application — delivering the correct malleability and sealing compression when torqued.
• Drop-In Installation — Dimensioned to the original specification, the 5000203708 seats correctly into its mating surface without reworking or shimming, supporting a clean, leak-free install.
• Verified Fitment for the DPU 100-70 — Confirmed for the DPU 100-70 reversible vibratory plate compactor (part number 5000008900), so you can order with confidence that this is the correct ring for your machine.
• Maintains Sealing Integrity — A correctly seated copper ring prevents fluid weepage at threaded or flanged connections; a failed or reused ring can lead to leaks that compromise lubrication or hydraulic pressure in the compactor's drive system.
• Fuel and Fluid System Safety — Copper sealing rings used in fuel or hydraulic circuits are a safety-relevant component; using the OEM-specified ring material ensures the joint meets the original design's pressure and temperature tolerances.

A copper ring (Ring Cu) is a soft-metal sealing element used at threaded ports, drain plugs, or banjo fittings to create a leak-proof joint between two metal surfaces. When the fastener is tightened, the copper deforms slightly to fill microscopic surface irregularities, forming a reliable seal against oil, fuel, or hydraulic fluid. Over time or after multiple removals, the ring loses its ability to conform and seal properly, making replacement with a correctly sized OEM part essential to preventing leaks during operation of the DPU 100-70.
