The Conversions Tech Tinned Copper Compression Lug is a seamless tubular connector for 3/0 AWG copper conductors terminated to 3/8″ studs. Engineered for power distribution, battery cabling, and grounding applications where reliable bolted connections are required. The seamless barrel construction provides uniform compression geometry, while tin plating delivers oxidation resistance for long-term electrical stability.

FAQ
What crimp tool is required for 3/0 AWG compression lugs?
Use a hydraulic or dieless compression crimp tool rated for 3/0 AWG copper lugs. Follow the tool manufacturer's die selection or index setting for seamless tubular lugs to achieve proper compression.
Is this lug rated for outdoor or wet location use?
The 600V rating and tin-plated finish provide baseline corrosion resistance. For outdoor or wet environments, seal the termination with adhesive-lined heat shrink to prevent moisture ingress at the conductor interface.
Can this lug be used with fine-stranded cable?
This lug is specified for 3/0 AWG copper conductors. Fine-stranded cable may require ferrules or verification of barrel ID (0.530″) against conductor diameter to ensure proper fill and compression.
