The Conversions Tech Copper Compression Lug is a seamless tubular electrical connector engineered for 4/0 AWG copper conductors and 1/2" stud terminations. Built from bare (non-tinned) copper, it provides maximum conductivity for high-current applications including battery cables, bus bars, switchgear, inverters, and industrial power distribution. The seamless barrel construction ensures uniform crimp compression and low joint resistance when installed with proper tooling.

Equivalent to standard heavy-duty compression lug form factors used across major electrical manufacturers. Conversions Tech lugs are engineered to US specifications and built to equivalent dimensional and performance standards at lower cost.
FAQ
What crimp tool is required for 4/0 AWG compression lugs?
Use a hydraulic crimping tool with dies rated for 4/0 AWG copper compression terminals. Follow the manufacturer's die selection chart and apply the specified number of crimps to the seamless barrel for proper compression and pull-out strength.
Is bare copper suitable for my application?
Bare copper provides maximum conductivity and is appropriate for controlled indoor environments, electrical rooms, and dry locations. For corrosive, marine, or outdoor environments, specify tin-plated lugs or seal terminations with adhesive-lined heat shrink tubing.
Can this lug be used for aluminum conductors?
No. This lug is specified for copper cable only. Using copper compression lugs on aluminum conductors requires proper transition methods and is not recommended without engineering review.
