Copper washer for Volvo

The copper washer is a sealing component used in Volvo heavy machinery to maintain system integrity. It functions by creating a seal between two mating metal surfaces when compressed, effectively preventing the leakage of liquids or gases in fluid circuits. This component is commonly utilized in fuel injection systems, hydraulic piping, and pneumatic connections where maintaining pressure is necessary for machine operation.

This part is identified by part number 13947630 and is designed for use across the Volvo equipment range, including excavators, wheel loaders, articulated haulers, and industrial engines. The washer is manufactured to specific dimensions to fit standard bolts and connection points within these systems. It is intended for applications where a consistent seal is needed to prevent fluid loss.

In general engineering practice, copper washers are used as crush gaskets in mechanical assemblies. Their material properties allow them to deform slightly under compression, which helps them conform to surface irregularities and provide a secure seal. These washers are typically replaced whenever a sealed connection is disassembled to ensure the continued hermeticity of the hydraulic, fuel, or pneumatic systems they serve.
