75 Pack M20 Flat Washer Copper Washer Sealing Rings, 20mm ID 26mm OD 1.5mm Thick

Descriptions

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
