The Wacker Neuson Copper Washer is a genuine OEM component designed for the RD10, RD15, and RD25 hydrostatic double drum vibratory tandem rollers. As a direct factory replacement, this copper washer meets the original material and dimensional standards set for these machines. It is confirmed to fit multiple RD-series configurations, making it a straightforward service part for operators and technicians maintaining their roller fleet.
Key Features
- Genuine OEM Copper Composition — Sourced directly from Wacker Neuson, this washer is produced from the same copper alloy specified at the factory, ensuring correct sealing performance and corrosion resistance in hydraulic and fluid-circuit applications.
- Drop-In Fitment for RD-Series Rollers — Engineered to match the original seat geometry on the RD10, RD15, and RD25 tandem rollers, so it seats correctly without reworking the mating surface.
- Broad RD-Family Coverage — A single part number covers multiple RD-series machine configurations, simplifying parts ordering for mixed fleets or multi-unit job sites.
- Leak Prevention at Critical Joints — Copper washers in hydraulic and fuel systems deform under torque to form a metal-to-metal seal. A worn or reused washer can fail to seat properly, leading to fluid seepage at fittings or drain ports.
- Hydraulic System Integrity — On hydrostatic drive rollers like the RD series, maintaining a clean, leak-free hydraulic circuit is essential for consistent drum speed, steering response, and compaction output. This washer supports that integrity.
A copper washer functions as a crush-type sealing element used at threaded fittings, drain plugs, and hydraulic ports. When the fastener is tightened, the soft copper deforms slightly to fill minor surface imperfections and create a reliable metal-to-metal seal that resists fluid leakage under pressure and vibration. Over time and through repeated service cycles, copper washers lose their ability to re-seal and should be replaced rather than reused — a fatigued washer risks slow leaks that can compromise hydraulic pressure or allow contaminants to enter the system.
