About This

What You Get: Each package contains 75 copper washers, inner diameter 30mm/1.18", outer diameter 36mm/1.42", thickness 2mm/0.08"
Pure Copper Material: Our washers are made of high-purity copper, offering exceptional thermal and electrical conductivity, and they are resistant to high temperatures, corrosion and rust, and can provide long-term service
Function: The pure copper flat washer is specifically designed to provide optimal electrical grounding and heat dissipation, while also preventing fastener loosening from vibration or thermal cycling in high-performance applications
How to Use: Before installation, ensure all contact surfaces are clean and free of debris. Place the pure copper washer evenly between the components to be sealed. Using appropriate tools, tighten the fasteners gradually avoid over-tightening to prevent deformation and maintain optimal sealing performance
Wide Applications: Suitable for automotive oil circuit sealing, hydraulic pipelines, home appliance compressors, ship salt water environment, and industrial equipment flange connections; can replace nylon or rubber gaskets for high-temperature conductive occasions, such as spark plugs, transformer grounding, gas valves, etc
