Wacker Neuson 5000128346 Ring Seal A6 X 10 Cu

The Wacker Neuson is a genuine OEM Ring Seal A6 X 10 Cu designed for DPU and DPS series reversible and single-direction vibratory plate compactors. This copper sealing ring is manufactured to Wacker Neuson's exact specifications, ensuring a proper seal wherever it is installed in the hydraulic or fuel system of your machine. Confirmed fitment spans a wide range of DPU and DPS models including the DPU 2440H, DPU 2540H, DPU 2550H, DPU 2560H, DPU 3050H, DPU 3060H, DPU 3070H, DPS 1850H, DPS2050H, DPU5545Heh US, DPU6555Heh US, DPU5260Hehb+ US, and DPU6275Hehb+ US, among others.

Key Features

• Copper Construction for Reliable Sealing — Made from copper (Cu) to the A6 X 10 specification, this ring compresses correctly under torque to form a leak-free seal — critical for maintaining system pressure integrity.
• Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part 5000128346 matches the original component exactly, with no dimensional guesswork or substitution risk.
• Drop-In Installation — Sized to the A6 X 10 standard, this seal ring seats directly into the original port or fitting without reworking threads or mating surfaces.
• Broad DPU and DPS Series Coverage — Compatible across a large range of DPU and DPS reversible and single-direction vibratory plate compactors, making it a smart stocking item for fleets running multiple Wacker Neuson plate models.
• Prevents Fluid Loss and Contamination — A worn or improperly seated seal ring allows fluid to weep past fittings, leading to pressure loss and potential ingestion of contaminants — replacing it promptly keeps the system operating as designed.

A copper seal ring is a small but essential sealing element used at threaded connections in hydraulic, fuel, or oil circuits. Its purpose is to deform slightly under the clamping force of a fastener, filling any microscopic surface irregularities between mating faces to prevent fluid from escaping past the joint. When a copper seal ring ages, it loses its ability to conform under load — the result is seeping fluid, loss of system pressure, or contamination ingress. Replacing it with the correctly sized and specified ring, such as the Wacker Neuson 5000128346, restores a clean, leak-free joint and protects surrounding components from fluid damage.
