Conversions Tech Tinned Copper Compression Lug – 4/0 AWG, 3/8″ Stud
The Conversions Tech Tinned Copper Compression Lug is a seamless tubular, heavy-duty electrical connector engineered for 4/0 AWG copper conductors and a 3/8″ stud interface. Manufactured from high-purity copper and fully tin plated, this lug provides excellent electrical conductivity, corrosion resistance, and long-term mechanical stability in high-current power distribution applications.
Its seamless barrel construction ensures uniform compression during crimping, minimizing electrical resistance while improving pull-out strength and vibration resistance. This compression lug is ideal for industrial power systems, battery cables, renewable energy installations, grounding conductors, and heavy-equipment electrical assemblies.
