Key Features
- Genuine Copper Construction — Copper material provides the ductility and thermal resistance needed for sealing under the high-pressure and heat conditions typical of concrete pump fluid systems.
- Direct OEM Replacement — Manufactured to the original equipment specification, this washer seats and seals exactly as the factory-installed component, with no rework or shimming needed at installation.
- Confirmed Fitment — Specifically matched to F4L1011 and MQC-180 concrete pump models, eliminating guesswork when ordering service parts for these machines.
- Leak-Free Sealing Performance — A correctly seated copper washer maintains a tight, pressure-rated seal at critical joints; a damaged or worn washer can lead to fluid leaks, pressure loss, and pump inefficiency.
- Fuel and Fluid System Safety — Used at fuel or hydraulic connection points, a proper-seating copper washer prevents seepage that could create fire hazards or fluid contamination on the jobsite.
A copper washer serves as a crush-type sealing element at threaded fastener joints, banjo fittings, or drain plugs within a machine's fuel, hydraulic, or cooling system. When tightened, the soft copper deforms slightly to fill microscopic surface irregularities, creating a leak-proof metal-to-metal seal that holds up under pressure and temperature cycling. When a copper washer becomes cracked, over-compressed, or corroded, it loses its ability to seal effectively, resulting in fluid weeps or full leaks that can compromise pump operation and create safety concerns on the work site.
