The Conversions Tech Copper Compression Lug is a seamless tubular connector engineered for terminating 1/0 AWG copper conductors to 5/16" studs. The bare (non-tinned) copper construction provides maximum electrical conductivity for high-current power distribution in controlled indoor environments. The seamless barrel design ensures uniform compression, forming gas-tight joints with minimal contact resistance and high pull-out strength. This lug is rated for 600V AC/DC and is suitable for battery terminals, bus bars, grounding points, and power distribution blocks where a compact hardware footprint is required.

FAQ
What crimp tool should I use for this 1/0 AWG lug?
Use a hydraulic or dieless compression crimp tool rated specifically for 1/0 AWG copper lugs. Verify die compatibility with seamless tubular barrel construction.
Can this bare copper lug be used outdoors?
This lug is designed for controlled or protected indoor environments. For outdoor or corrosive environments, specify a tin-plated version or seal the connection with adhesive-lined heat shrink tubing to prevent oxidation.
What is the correct strip length for installation?
Strip conductor insulation to 0.680" before crimping. This matches the barrel length and ensures full conductor insertion for proper compression and electrical contact.
