The Conversions Tech Tinned Copper Compression Lug is a seamless tubular electrical connector engineered for 4 AWG copper conductors and 3/8″ stud terminations. Manufactured from seamless copper with a tin-plated finish, this lug provides corrosion resistance and stable electrical contact in power distribution, grounding, and battery applications.
The seamless barrel construction promotes uniform compression during crimping, reducing joint resistance while maintaining mechanical integrity under vibration and thermal cycling. The 3/8″ stud interface suits bus bars, distribution blocks, battery terminals, and industrial grounding points.

FAQ
What crimp tool is required for 4 AWG compression lugs?
Use a compression crimp tool rated for 4 AWG copper lugs. Follow the tool manufacturer's die selection and pressure settings.
Is this lug rated for aluminum conductors?
No. This lug is designed for copper conductors only. For aluminum applications, specify an AL/CU-rated connector.
What is the recommended strip length for proper termination?
Strip conductor insulation to 0.630″ to ensure full insertion into the barrel before crimping.
